Clause Requirement – Test Result – Remark Verdict

SECTION 4.1: Utility compatibility 4.1.1 General P 4.1.1.1 This clause describes the technical issues and the

responsibilities related to interconnecting an embedded generator to a utility network. Subclauses 4.1 and 4.2 are based on IEC 61727:2004.

Noticed. P

4.1.1.2 The quality of power provided by the embedded generator in the case of the on-site a.c. loads and the power delivered to the utility is governed by practices and standards on voltage, flicker, frequency, harmonics and power factor. Deviation from these standards represents out-of-bounds conditions. The embedded generator is required to sense the deviation and might need to disconnect from the utility network.

Noticed. P

4.1.1.3 All power quality parameters (voltage, flicker, frequency and harmonics) shall be measured at the PUC, unless otherwise specified (see annex A). The power quality shall comply with NRS 048-2. This implies that the combined voltage disturbances caused by the specific EG and other customers, added to normal background voltage disturbances, may not exceed levels stipulated by NRS 048-2. NOTE The frequency cannot be changed by an EG.

See appended table and Annex No. 1 – EMC Test Report.

P

4.1.1.4 The embedded generator’s a.c. voltage, current and frequency shall be compatible with the utility system in accordance with IEC 61727.

Noticed. P

4.1.1.5 The embedded generator shall be type approved, unless otherwise agreed upon with the utility (see annex A).

Noticed. P

4.1.1.6 The maximum size of the embedded generator is limited to the rating of the supply point on the premises.

Rely in the responsibility of the installer.

N/A

4.1.1.7 Embedded generators larger than 10 kW shall be of the three-phase type. NOTE This value refers to the maximum export potential of the generation device.

All inverters are three-phase type.

P

4.1.1.8 A customer with a multiphase connection shall split the embedded generator over all phases if the EG is larger than 6 kW. NOTE 1 Balancing phases in a multiphase embedded generator is deemed desirable.

SECTION 4.1: Utility compatibility 4.1.2 Normal voltage operating range P 4.1.2.1 In accordance with IEC 61727, utility-interconnected

embedded generators do not normally regulate voltage, they inject current into the utility. Therefore the voltage operating range for embedded generators is designed as protection which responds to abnormal utility network conditions and not as a voltage regulation function.

Derived from tests. P

4.1.2.2 The embedded generator shall synchronise (see 4.1.8) with the utility network before a connection is established. The embedded generator shall not control the voltage, unless agreed to by the utility (see annex A).

See appended table. P

4.1.3 Flicker The operation of the embedded generator, in conjunction with other existing and future loads at the same point of connection, shall not cause flicker levels to increase beyond the levels specified in NRS 048-2.


P

4.1.4 DC injection The static power converter of the embedded generator shall not inject d.c. current exceeding 1 % of the rated a.c. output current into the utility a.c. interface under any operating condition in accordance with IEC 61727. This relates specifically to embedded generators where the static power converter has no simple separation from the utility network (e.g. inverters that are transformer-less).


4.1.5 Normal frequency operating range An embedded generator that operates in parallel with the utility system shall operate within the frequency trip limits defined in 4.2.2.3.3.

SECTION 4.1: Utility compatibility 4.1.6 Harmonics and waveform distortion

(in accordance with IEC 61727) P

4.1.6.1 Only devices that inject low levels of current and voltage harmonics will be accepted; the higher harmonic levels increase the potential for adverse effects on connected equipment.


P

4.1.6.2 Acceptable levels of harmonic voltage and current depend upon distribution system characteristics, type of service, connected loads or apparatus, and established utility practice.


P

4.1.6.3 The embedded generator output shall have low current-distortion levels to ensure that no adverse effects are caused to other equipment connected to the utility system.


P

4.1.6.4 Total harmonic current distortion shall be less than 5 % at rated generator output in accordance with IEC 61727. Each individual harmonic shall be limited to the percentages listed in table 1.


P

4.1.7 Power factor The embedded generator shall not inject reactive power into the utility network, while the drain of reactive power shall be limited to a power factor of 0,9. These limits apply, unless otherwise agreed upon with the utility (see annex A).


4.1.8 Synchronization P 4.1.8.1 The embedded generator shall synchronize with the

utility network before the parallel connection is made. Derived from tests. P

4.1.8.2 Automatic synchronization equipment shall be the only method of synchronization.


4.1.8.3 The limits for the synchronizing parameters for each phase are

SECTION 4.2: Safety and protection 4.2.1 General

The safe operation of the embedded generator in conjunction with the utility network shall be ensured at all times.

Noticed. P

4.2.2 Safety disconnect from utility network P 4.2.2.1 General

The embedded generator shall automatically and safely disconnect from the grid in the event of an abnormal condition. Abnormal conditions include

a) network voltage or frequency out-of-bounds conditions,

b) loss-of-grid conditions, and d.c. current injection threshold exceeded.


4.2.2.2 Disconnection switching unit P 4.2.2.2.1 The embedded generator shall be equipped with a

disconnection switching unit which separates the embedded generator from the grid due to the above abnormal conditions. The disconnection unit may be integrated into one of the components of the embedded generator (for example the PV utility-interconnected inverter) or may be an independent device installed between the embedded generator and the utility interface.

The transformer less inverter provides two relays in series for each line.

P

4.2.2.2.2 The disconnection switching unit shall be able to operate under all operating conditions of the utility network.

The disconnection switching unit was tested according the single fault safety of the VDE0126-1-1. See appended table.

P

4.2.2.2.3 A failure within the disconnection switching unit shall lead to disconnection and indication of the failure condition.


4.2.2.2.4 A single failure within the disconnection switching unit shall not lead to failure to disconnect. Failures with one common cause shall be taken into account and addressed through adequate redundancy.

The disconnection switching unit was tested according the single fault safety of the VDE0126-1-1. See appended table.

SECTION 4.2: Safety and protection 4.2.2.2.5 The disconnection switching unit shall disconnect from

the network by means of two series switches. Each switch shall be separately rated to the embedded generator’s nominal power output. At least one of the switches shall be an electromechanical switch while the second switch may be part of the existing solid state switching circuits of a utility-interconnected static power converter. The electromechanical switch shall disconnect the embedded generator on the neutral and the live wire(s). NOTE 1 The switching unit need not disconnect its sensing circuits. NOTE 2 A mains-excited induction generator requires only a single disconnection switch as the generator requires excitation from the utility network to operate. NOTE 3 A static power converter without simple separation should make use of two series-connected electromechanical disconnection switches.

The transformer less inverter provides two relays in series for each line.

P

4.2.2.2.6 The fault current breaking capacity of the disconnecting switch shall be appropriately sized for the application.

See Annex No. 2 – Datasheet of the relay.

SECTION 4.2: Safety and protection 4.2.2.3 Overvoltage, undervoltage and frequency P 4.2.2.3.1 General

Abnormal conditions can arise on the utility system and requires a response from the connected embedded generator. This response is to ensure the safety of utility maintenance personnel and the general public, and also to avoid damage to connected equipment. The abnormal utility conditions of concern are voltage and frequency excursions above or below the values stated in this clause. The embedded generator shall disconnect if these conditions occur.


4.2.2.3.2 Overvoltage and undervoltage The embedded generator shall cease to energize the utility distribution system should the network voltage deviate outside the conditions specified in table 2. This applies to any phase of a multiphase system. The system shall sense abnormal voltage and respond. The following conditions shall be met, with voltages in r.m.s. and measured at the PUC. NOTE All discussions regarding system voltage refer to the nominal voltage. The purpose of the allowed time delay is to ride through short-term disturbances to avoid excessive nuisance tripping. The generator does not have to cease to energize if the voltage returns to the normal utility continuous operating condition within the specified trip time. A customer with a multiphase connection and a single-phase embedded generator above 3 kW shall monitor all phases for out-of-bounds voltage conditions. The EG shall be disconnected if an out-of-bounds voltage condition is detected on any of the phases.


4.2.2.3.3 Overfrequency and underfrequency The embedded generation system shall cease to energize the utility network when the utility frequency deviates outside the specified conditions. When the utility frequency is outside the range of 47,5 Hz and 52 Hz, the system shall cease to energize the utility line within 0,5 s in accordance with EA Engineering Recommendation G83/1-1: Amendment 1-June 2008. The purpose of the allowed range and time delay is to allow continued operation for short-term disturbances and to avoid excessive nuisance tripping in weak utility system conditions. The plant does not have to cease to energize if the frequency returns to the normal utility continuous operating condition within the specified trip time.

SECTION 4.2: Safety and protection 4.2.2.4 Prevention of islanding P 4.2.2.4.1 A utility distribution network can become de-energized

for several reasons: for example, a substation breaker that opens due to a fault condition or the distribution network might be switched off for maintenance purposes. Should the load and (embedded) generation within an isolated network be closely matched, then the voltage and frequency limits may not be triggered. If the embedded generator control system only made use of passive voltage and frequency out-of-bounds detection, this would result in an unintentional island that could continue beyond the allowed time limits.


4.2.2.4.2 In order to detect an islanding condition, the embedded generator shall make use of at least one active islanding detection method. An active islanding detection method intentionally varies an output parameter and monitors the response or it attempts to cause an abnormal condition at the utility interface to trigger an out-of-bounds condition. If the utility supply is available, the attempt to vary an output parameter or cause an abnormal condition will fail and no response will be detected. However, if the utility supply network is de-energized, there will be a response to the change which can be detected. This signals an island condition to the embedded generator upon detection of which the embedded generator shall cease to energize the utility network within a specific time period.


4.2.2.4.3 Active islanding shall be detected in all cases where the EG interfaces with the utility network through one or more static power converters.


4.2.2.4.4 Synchronous generators, power-factor corrected induction generators and self-excited induction generators shall use an islanding detection method acceptable to the utility (e.g. rate-of-change-of-frequency or voltage vector shift detection). Mains-excited induction generators are not required to be fitted with such islanding detection capabilities.


4.2.2.4.5 This section of NRS 097-2 requires that an islanding condition shall cause the embedded generator to cease to energize the utility network within 2 s, irrespective of connected loads or other embedded generators. The embedded generator shall comply with the requirements of IEC 62116 (ed. 1). NOTE Prevention of islanding measures are only considered on the embedded generator side, i.e. no utility installed anti-islanding measures are considered.


4.2.2.4.6 The embedded generator shall physically disconnect from the utility network in accordance with the requirements in 4.2.2.2.

The transformer less inverter provides two relays in series for each line. Derived from tests.

SECTION 4.2: Safety and protection 4.2.2.5 DC current injection

The static power converter of the embedded generator shall not inject d.c. current greater than 1 % (see IEC 61727:2004) of the rated a.c. output current into the utility interface under any operating condition. The EG shall cease to energize the utility network within 500 ms if this threshold is exceeded.


4.2.3 Response to utility recovery After a voltage or frequency out-of-range condition that has caused the embedded generator to cease energizing the utility network, the generator shall not re-energize the utility network for 60 s after the utility service voltage and frequency have recovered to within the specified ranges.


4.2.4 Isolation P 4.2.4.1 The embedded generator shall provide a means of

isolating from the utility interface in order to allow for safe maintenance of the EG. The disconnection device shall be a double pole for a single-phase EG, a three-pole for a three-phase delta-connected EG, and a four-pole for a three-phase star-connected EG. The grid supply side shall be wired as the source.

Disconnecting device is not integral part of the unit. The installation instructions specify a disconnection device for the final installation. The correct assembling is part of the installer.

N/A

4.2.4.2 The breaking capacity of the isolation circuit-breaker closest to the point of utility connection shall have a minimum fault current level of 6 kA in accordance with SANS 60947-2.

Rely in the responsibility of the installer and is stated in the installation instruction of the manufacturer.

N/A

4.2.4.3 This disconnection device does not need to be accessible to the utility.

P

4.2.5 Earthing P 4.2.5.1 The electrical installation shall be earthed in accordance

with SANS 10142-1. The earthing requirements for different embedded generation configurations in conjunction with the customer network are described in annex B for the most common earthing systems.

separation shall make use of earth leakage circuit-breakers which are able to respond to d.c. fault currents including smooth d.c. fault currents (i.e. without zero crossings) unless the inverter can exclude the occurrence of d.c. leakage currents through its circuit design1). NOTE The earth leakage unit may also fulfil the requirement of the all-pole disconnection device as stated in 4.2.4. 1) The appropriate earth leakage unit should be selected to accommodate the higher leakage current of inverters without transformers to avoid nuisance tripping.

The inverter was tested according IEC 62109-1 for the residual current device (RCD) or monitoring (RCM).

Note: *The stationary deviance of dc% is more relevant than the dynamic deviance of dmax at starting and stopping. Mains Impedance according EN61000-3-11: Rmax = 0,24 Ω; jX max= 0,15 Ω @50Hz (|Zmax| = 0,472 Ω) for single phase inverter use also R n = 0,16 Ω; jX n= 0,1 Ω Calculation of the maximum permissible grid impedance at the point of common coupling based on dc: Zmax = Zref * 3,3% / dc(Pn) The tests should be based on the limits of the EN 61000-3-11 for more than 16A.

Note: For under-frequency testing the applied frequency is varied from fn down to fth-low -0,1 Hz in steps of 0,025 Hz with a time duration per step exceeding the configured disconnection time. The operate value is the value of the applied frequency at switch the protection function trips and shall be within fth-low ± 0,05 Hz. For over-frequency testing the applied frequency is varied from fn up to fth-high + 0,1 Hz in steps of 0,025 Hz with a time duration per step exceeding the configured disconnection time. The operate value is the value of the applied frequency at which the protection function trips and shall be within fth-high ± 0,05 Hz.. The oscilloscope pictures below show the measured worst case disconnection times.
