3.4.1.2 Database Synchronisation:

16

Representative of BBMB informed that in 8th Test meeting, the difficulties being faced during

database modification and synchronization process was deliberated and to overcome these problems

some proposals were suggested, but none of them have been implemented so far. Lot of problems

are being faced in maintaining the availability of real time data at BBMB, SLDC in the absence of

proper database synchronization procedure. He mentioned that the issue was discussed in detail in

the 10th meeting of TeST and after detailed deliberations it emerged that there were several similar

issue, which needs proper coordination with concerned vendors. It was decided that a meeting

would be arranged at NRPC, New Delhi with all the concerned vendors of ULDC scheme and the

concerned State utilities to discuss and resolve the issues.

Representative of NRLDC informed that database synchronization activity was being done on

monthly basis. This only includes synchronization of domain data. However, ICCP and TNA

database is to be maintained individually by each control centers. NRLDC would share the ICCP

database before database synchronization to facilitate ICCP configuration by Constituents.

Members agreed for the same.

3.4.1.3 Running of State Estimator:

BBMB representative informed that despite 100 % telemetry, BBMB was facing problems in

keeping the State Estimator running due to Database Synchronization issues. He mentioned that

BBMB has 100% telemetry of all its stations and all the circuit breakers and isolators are wired and

reporting. However, on account of power system changes in other constituents, the TNA model is

updated by respective constituent in their own database but the same is not propagated to other

constituents.

The matter was discussed in various meetings, but issue remained unresolved. After detailed

deliberations, it was decided that training of one week duration would be arranged at each

constituent location, so that utilities are able to resolve issues in running state estimator.

BBMB representative, further requested that the underlying problems relating to database up-dation

and maintenance of TNA Model may also be resolved in consultation with M/s SIEMENS during

training so that the State Estimator can function smoothly.

It was informed that in its last meeting, NRPC had approved the training on state estimator.

However, the training could not be arranged as some of the members were of the opinion that data

synchronization issues should be resolved before training. But, M/s SIEMENS had conveyed that

updation of entire data base & synchronization can not be taken up during training due to paucity

of time. This activity is to be done by the utility himself, M/s SIEMENS may only help utilities in

carrying out this activity. It was clarified that without telemetry and updated data, running of state

estimator can not be ensured even after training.

Representative of NRLDC informed that database synchronization activity is being done by them at

NRLDC on monthly basis. This only includes synchronization of domain data. However, ICCP and

TNA database is to be maintained individually by each control centers. The State Estimator model

needs to be tuned by the constituents based on the availability of the telemetered data. It was also

clarified that the addition of stations in the network, which was prepared at the time of SAT, needs

17

to be done by the constituents.

After detailed deliberation representatives of all the SLDCs present in the meeting had agreed that

training should be arranged at the earliest. All the SLDCs would endeavor to resolve the issues

related to data base updation.

India had circulated the IPv6 Deployment Roadmap to all the Central Government

Ministry/Department/State/UTs to facilitate them in the task. He added that all the Government

Organizations were advised to follow a phased transition approach depending on the complexity

and the IPv6 readiness of their current networks and systems. Accordingly, it was suggested that the

SCADA/EMS System, which was under procurement at that time, may be got configured on IPv6.

He suggested that since the commissioning of new SCADA/EMS System has been completed,

POWERGRID may implement the roadmap for transition of SCADA/EMS IT System from IPv4 to

IPv6, which is to be completed by Dec., 2017.

Representative of POWERGRID informed that equipment in ULDC- II is compatible to IPV6 but

since most of existing network is in IPv4, it was integrated with IPv4. He opined that since

downward compatibility is not available in IPV6 , migration to IPv6 may be difficult till all

connected network migrates from IPv4 to IPv6.

The sub-Committee advised POWERGRID to take up the matter with the vendor and apprise the

sub-committee about the outcome.

A2. Presentation by Vendors on Latest Developments in SCADA and Communication equipment

A 2.1 Presentation was made by ABB, GE, Motorola (MB control) and Synergy Systems and members

were apprised about the latest developments in SCADA and Communication equipment.

T1: Table Agenda by PSTCL:

1. PSTCL representative informed that Nokia Mux was phasing out. He requested for suitable

replacement to ensure healthy Communication System especially at 220kV Barnala and 220kV

Malerkotla, as no SDH is installed there, besides 220kV Lalton Kalan, 220kV Gobindgarh-1,

220kV Jamsher.

POWERGRID representative informed that replacement was not possible. He suggested that

PSTCL should take action for replacement.

2. PSTCL representative informed that 4 Nos. Battery Chargers and associated Dry Battery were

required at sites- Malerkotla, Barnala, Gobindgarh-1 and Jagraon as these stations have Lead Acid

Batteries which were installed by PGCIL during the up gradation/replacement of Microwave

27

Towers with OPGW system and the same were being used for OPGW till date. Now these need

replacement with Dry type VRLA Batteries as these equipments have outlived their useful lives.

POWERGRID representative informed that replacement of batteries is the responsibility of PSTCL

and requested PSTCL to take necessary action .

3. PSTCL representative informed that data transmission from 400kV Nakodar was very critical as it

is inter-state LILO point, 400kV data from Talwandi Sabo being a generator is also a crucial one

along with 400kV Muktsar data, too. Hence provision may be made so that data for afore-

mentioned 3 Nos. sub-stations may directly respond to SLDC Ablowal via 400kV Moga sub-station

instead of present data route which is being followed via 220 kV Moga.

POWERGRID representative agreed on the same and informed that they will explore the options to

consider PSTCL proposal for necessary action.

4. PSTCL informed that in order to minimise frequent tripping/burning of PDH cards at 220KV S/Stn.

Moga, separate earthing of carrier room of said S/Station. was being carried out. Planning & Design

was complete. Tenders would be opened on 10.07.2017 and work order would be issued. Separate

earthing of carrier room is likely to be completed before 31.07.2017.

This issue was covered under item 2.2.2.

5. PSTCL representative informed that names of 5 officers were conveyed to NRPC. He requested

that training may be imparted to them.

This issue was covered under item 3.5.
