2 •••• Human-Machine Interface (HMI) GEI-100485 Product Description

IntroductionThe Human-Machine Interface (HMI) is powerful, flexible, and user-friendlyoperator interface with functions for real-time control and monitoring. The HMI canbe configured as an operator interface for a variety of equipment, such as gasturbines, steam turbines, hydraulic turbines, generator excitation systems, staticstarters, compressors, heat recovery steam generators (HRSGs), and balance of plant(BOP) auxiliaries.

Today, more power generation units and functions are becoming integrated toachieve higher efficiencies with improved reliability and operator visualization. Thisrequires that HMI systems deliver process information from a broader spectrum ofcontrollers and computer platforms. Operators are demanding a comprehensivesolution to meet their requirements, no longer accepting multiple interface systems,each dedicated to their respective control systems.

The HMI system is playing an increasing role in delivering information to othermembers of the business management team. Users are demanding more integratedHMI systems to measure total plant operating efficiency, regulatory values, and datafor business analysis. This means that future HMI systems must be able to access anddeliver information to the business enterprise system as well as communicate to BOPcontrol systems. Such enhanced functionality requires a more integrated solutionusing open operating systems and hardware platforms.

Systems span from simpleretrofits involvingreplacement of a singleexisting <I> processor tocomplete HMI or IndustrialControl Systems (ICS)systems on new plantinstallations.

The HMI system infrastructure meets these demanding requirements. Its opensystem design uses standard hardware and operating system software. The HMI�ssoftware system uses the Microsoft Windows NT client-server architecture.Windows NT provides built-in multi-tasking, networking, and security features. Theability to run the system on conventional PC-based platforms minimizes cost,promotes open interfaces, permits system scalability, and ensures longevity ofinvestment and future performance enhancement.

System ConfigurationThe HMI system incorporatesGE�s latest technology toproduce a superior productfor the power generationindustry.

The HMI system integrates plant operation at a single level. Plant operators andengineers can view and control plant equipment using a common interface. The HMIhardware platform uses conventional PC hardware running the Windows NToperating system. Turbine specific application software is used as the core softwarefor system maintenance, troubleshooting, and operation. GE Fanuc�sCIMPLICITY® HMI software is utilized for graphical interface and some supportfunctions.

The HMI provides a common view for the operators and maintenance personnel intothe system equipment. Interconnections for plant control, display, and dataaccumulation are made through ARCNET and/or Ethernet data highways.

Graphics and AlarmsThe HMI provides the required access to control systems for operation andmaintenance of the process. The HMI uses the graphics and alarm features of theCIMPLICITY software to provide the seamless integration of controls from a varietyof applications.

The graphic displays offer realistic, 3-D viewing in a real-time environment,providing superior monitoring capabilities over other systems. Because the keyfunctions of the HMI are the display of data and processing of operator commands,the screens show a variety of signals, including their values and units. Display itemschange color based on logic signals, while certain objects are dynamic and refreshwith every data update, like bar graphs. High-speed viewing allows the displayeddata to be updated once per second, and special tools allow for collection and storageof data at rates as fast as 10 ms.

HMI graphic displays include main unit, vibration, sensor readings, control setpoints,alarms, permissives, logic forcing, demand display, sequence editor, dynamic rungdisplay, trip history display, trending, and many others depending on the application.

Standardized GraphicsThe HMI screens are developed using preconfigured graphic building blocks thatbrings commonality to all screens used in a turbine, HRSG, BOP, exciter, or anyapplication using the HMI. These building blocks also permit easy and consistentscreen development or modification.


Enhanced Navigation• Allows access to any screen

• Selected screen is indicated by a highlighted button

Real-Time TrendsHMI trending allows analysis of the HMI data on a real-time scale with:

• Multiple charts per graphic screen

• Default parameters for easy setup; fully configurable by the user

• Unlimited number of points per screen

• Configurable colors, fonts, line styles, and legend

• Different plotting rates per pen

• Ability to dynamically switch pens

• Separate axis available for each pen

• Ability to scroll forward and backward through plotted areas

• Smooth and step lines

• User definable labels for pen lines

• Ability to dynamically change trends at runtime

Pre-Configured Short Term Trend Files• Startup

• Exhaust thermocouples

• Bearing metal and drain temperatures

• Seismic vibration

• Wheelspace temperatures

Quick TrendQuick Trends allows a user to select any point on an operator screen, which displaysa dialog box pop-up menu for that point without having to preconfigure the trend.

Alarm ViewerAlarm Viewer allows you to view alarms from any HMI on the network.

With the click of a mouse, thestatic alarm view can beupdated to display currentalarms.

It supports both dynamic and static modes. Dynamic mode displays alarms as theyoccur. Static mode allows the operator to freeze the scrolling as needed to address analarm condition. Meanwhile, the HMI software continues to monitor and record allnew alarm events.


Alarm ManagementThe HMI's Alarm Management helps the operator respond appropriately to alarms. Itincludes the following:

• Main alarm display with all plant alarms

• Alarm lockout for toggling alarm conditions. Locked alarms continue to berepresented on the unit or plant alarm displays, so that an active alarm isdisplayed as either active or locked.

• An alarm notepad function that allows the operator to add an explanatory note toeach active alarm drop number for each panel. These notes can be viewed fromthe alarm display.

• Control system equipment diagnostic alarm display. Operators can recognizethese separately from regular alarms or events.

• Alarm printing to print all alarms, only process alarms, or only diagnosticalarms.

CommunicationsFor Ethernet TCP/IP communication to third party equipment (such as DCSsystems), the HMI provides GE standard messages (GSM) and Modbus protocol.GSM application layer protocols support four classes of application level messages:administration, event-driven, periodic data, and common request messages (refer toGEI-100165 for the protocol format).

The speed of this interfacemay limit the amount of datathat can be accommodated.

Alternatively, communication to remote distribution control system (DCS)equipment is available through a Modbus interface, where the HMI acts as a slave tothe DCS master. Such a system allows an operator at a remote location to initiate anyoperator command, and to monitor data from the Mark V and Mark VI controllersignal database.

Optional Functions

HistorianThe HMI supports a Windows NT-based Historian computer, which collects andstores data from the control units for later analysis. The GE Historian, usingproportional integral (PI) and PI-Process Book software from OSI Software,provides a package designed to collect, store, and present archival plant data. Datatime-tags are retained, and data can be analyzed by Process Book or by exporting toa variety of commercial spreadsheet or database programs.

Note The Historian gathers its data directly from the control network. Historiandata for display by the HMI and other systems is passed over the Ethernet datahighway.

The HMI can access the historical data for certain structured functions using thehistorical data plot program and historical alarm and event report.

A historical data plot program plots up to six historical points versus time. Theoperator can specify the start time, elapsed time, list of points and scaling. The HMIplots can be displayed, printed, or saved to a file for further processing. Multipleplots can be displayed simultaneously.


The historical alarm and event report displays alarms, events and sequence of events(SOE) for a specified time range, in a format similar to the normal alarm display.The report can be displayed, printed, or saved to file.

Timesync FunctionTime synchronization capability is provided in the HMI, in both low and highresolution forms. Redundant time masters can be used in any combination of low orhigh resolution masters. When redundant masters are available, all Turbine controlpanels and operator interface units automatically select the same, highest qualitytime master. Failure of the selected master results in selection of another commonmaster by the entities on the link.

PC TimesyncThe low-resolution form of time synchronization is based on local HMI PC clocks.This form holds slave PCs within a steady-state error of ± 250 ms of the master PC�sclock.

IRIG-BThe high resolution form of time synchronization uses an optional processing boardin the PC. It can track externally generated IRIG-B modulated time code signals, toproduce synchronization with a steady-state error of ± 1 ms. GPS receivers for theIRIG-B signals can be provided by either GE or the customer.

Application-Specific FeaturesThe base HMI package is expanded when turbine control application software isadded. The Mark V and Mark VI turbine controls add significant features unique toeach control system.

SPEEDTRONICTM Turbine ControlWhen the HMI is paired with either the Mark V or the Mark VI turbine control, theturbine control software tools can be added to as an integral part of the HMI. Theturbine control is based on the GE Control Systems Toolbox (toolbox). The HMIbecomes an even more powerful interface by adding maintenance andtroubleshooting functions described in the following table.


Maintenance and Troubleshooting Functions

Function Mark V Mark VI DescriptionDemand Display � � Gives the operators and technicians a special easily configured screen

that displays multiple data to help troubleshoot system problems. Simplecommands may also be issued from this screen, eliminating the need tojump back and forth between several screens.

Logic Forcing � � Enables the user to force logic signals within the control sequencing. Thisallows faster and easier forcing of critical control signals to enhancetroubleshooting of the turbine control process and the Mark V and Mark VIcontrol.

Dynamic RungDisplay

� � Is a live display of the sequencing status. This provides the user a quickcheck of the control status for more precise troubleshooting of turbine andcontrol status.

Prevote Data Display � Shows the status of the three primary controllers in a TMR control system,which allows quicker pinpointing of problems.

Control Constants � � Can be viewed and changed without the need to shutdown andreconfigure the database.

Autocalibrate � � Provides a quick and easy function to calibrate the stroke of turbinedevices at the control panel without having to install costly delicate andtime-consuming precision measuring equipment at the turbine device.

Trip History � Collects a set of data for a trip history to enable analysis of trip events.The data set covers a time frame that spans the actual trip. On a tripevent, the HMI collects the trip history data from the turbine controller toavoid it being overwritten. The trip history data can be plotted, printed astabular data, or transmitted electronically for remote analysis. The dataset for the previous nine trip events for each turbine control is retained.

Trip History � Captures critical turbine trip data captured in a capture block. The sizeand specifications of the capture block is set up by the user and utilizesthe Data Historian utility that is part of the Mark VI toolbox softwareproduct. The trip log can be viewed with the toolbox.

Reactive CapabilityDisplay

� � Shows an X-Y display of real and reactive power. The plot shows threelines of generator capability as a function of generator coolanttemperature or hydrogen pressure.

Manual SynchronizingDisplay

� Provides a graphical display of a synchroscope and other criticaloperating parameters that allows manual synchronization of the generatorbreaker from a HMI.

Hold List � Is for steam turbine systems that have Automatic Turbine Startup (ATS)functions. The hold list is a set of conditions that must be met at certaintimes, speeds, and operating modes in the turbine startup. The HMIprovides for the creation, modification, display, printing, down anduploading, compiling, and reverse translation of a hold list of up to 64points.

Diagnostic CountersDisplay

� � Provides information on internal control and I/O card functions used fortroubleshooting and/or statistical data gathering.

Control Signals � � Can be displayed on dedicated screens as Events (any database signal)or as SOE (contact inputs). The SOE data is timetagged to 1 ms providinga powerful troubleshooting tool.

Timer/CounterDisplay

� � Shows accumulated running times for equipment. For a gas turbine, thiswould be a fired-hours counter or starts counter.

Configuration Tools � For maintaining and modifying the Mark V system parameters are part ofthe Mark V toolset. These parameters include such items as I/Oconfiguration, control constants, sequencing and trip logs.


ICS/BOP ControlWhen the HMI is used in our ICS product line or as a BOP control interface then thetoolset from the ICS/BOP product becomes part of the HMI and the HMI can beexpanded to include the maintenance and troubleshooting functions contained in theapplication software.
