Introduction

• In order to meet the nation’s demand in the new millennium, Tenaga Nasional Berhad has designed Stesen Janaelektrik Manjung with capacity of 3 x 700 MW (2100MW) coal fired power plant. At present, Stesen Janaelektrik Manjung will be operating as Independent Power Plant of TNB and will be known as TNB Janamanjung Sdn. Bhd. which is fully owned by Tenaga Nasional Berhad. It is required to supply electric power to TNB via a Power Purchase Agreement (PPA).

• TNB Janamanjung is also operating as a strategic business enterprise (SBE) under the Generation Division of TNB.The responsibility comes along; all Stesen Janaelektrik Manjung staff are expected to perform up to the required competency level. Every tripping at the station will cost the loss of revenue millions per day/unit. Hence, these incidents can be reduced through proper training programs and services provided.

• In line with that, Tenaga Nasional Berhad agreed fo TNB Janamanjung to undertake a project to develop, construct and commission a full-scale real time PC-based simulator base on the actual 3 X 700 MW coal fired Stesen Janaelektrik Manjung. This simulator system will be used to retrain and upgrade the competency and capability skills of Stesen Janaelektrik Manjung technical staffs. The project has been awarded to NJSB-RDE JV and kick-off date was on 3rd July 2006. The 20 months project will be completed on 3rd March 2008

Simulator Definition

• A simulator is a complex system of hardware and software packages assembled and configured according to each customer's specific requirements.
• A power station training simulator is a training tool designed to replicate the steady state and dynamic responses of a power station to operator actions. In its simplest form, a simulator is a combination of:
• mathematical models of the plant that "trick" a control system into thinking it is controlling real plant control system emulation man-machine interface. There are several type of simulators :

1. Replica power plant simulators

• Replica power plant simulators with emulated controls and MMI
• Replica power plant simulators with stimulated controls and MMI
• Replica power plant simulators with hybrid controls and MMI

2. Generic simulators

3. Part task simulators

Replica power plant simulators with emulated controls and MMI

• Replica simulator closely simulates the reference plant configuration, control system, operator interface, and information system

• In emulation type simulator the functions of the reference plant control system and Human Machine Interface (operator interface) are simulated using alternative or equivalent off-the-shelf open systems hardware and software and VDU based graphics systems to reproduce the HMI functions.

Replica power plant simulators with stimulated controls and MMI

• In the stimulation type simulator the control system and the HMI are simulated by using the same control system and HMI as in the reference plant. (The hardware and software for the HMI and control system are same as in the real plant).

Replica power plant simulators with hybrid controls and MMI

• In the hybrid type simulator the control system and the HMI used are the same as in the reference plant but the hardware to perform the function is different or emulated. (The software for the HMI and control system are same as in the real plant but the hardware eg. I/O card is different or been emulated).

Simulator Principle Function

1. To enable experienced operating and maintenance staffs to familiarize themselves with the reference plant control system and operator interface before being required to operate an maintain the existing reference plant system;
2. To train new operators in the details of the reference plant and operating and maintenance procedures;
3. To provide revision for experienced operations and maintenance personnel (refresher training); and
4. To test control system configurations and graphics.
5. To enhance reference plant personnel particularly operations competency level.
6. To assist the reference plant top management in implementing succession planning that includes training and certificating a Patrolman identified to take over a Unit Operator.
7. To develop a competency database those complements and add value to the Human Resource requirements.
8. To assist the reference plant top management in developing career path and providing motivation for the staff of the reference plant.
9. To enhance the bottom line of the reference plant that includes simulating a reference plant malfunction and near misses.

Simulator Major Components And Its Functions

Hard Panel

• Hard Panel is used when there is requirement from the customer. Some prefer hard panel to instill "what you see is what you get" feeling in simulator. Some people think hard panel soft simulation is adequate. Current trend is more people opt for hard panel soft simulation since the operation in control room nowadays use normal PC and a lot of thing have been migrated to software.

Soft Panel

• The Mimic Client design approach focuses on ease of use and the ability to display and ease navigate complex Panel Mimics with fast update and realistic operation of panel input. In interactive mode the Mimic Client uses panel mimics to operate the simulator without hard panel. In non-interactive mode the Mimic Client show the status of the output devices.
• Panel Mimics are replications of control desk and panel sections. All meters, recorders, push buttons, switches, lamps, and potentiometers are shown in a realistic symbol representation. The actual status of panel objects is shown, e.g. by color change, blinking etc. Panel Mimics don't show the contents of displays.Typically a top level panel mimic shows an overview of the panel from which a particular panel mimic can be selected.

The combustion of fuel at every burner level is simulated including the generation of gaseous combustion products such as CO, CO2, SO2, N, H2O, O2 as well as ash and combustion residues due to incomplete combustion of fuel.

• The simulation also considers that incomplete combustion at one or more burners may, depending on ignition conditions, cause the ignition (secondary combustion) of the unburned fuel further up in the furnace. The model also takes into account fuel water content, coal burner efficiency, coal particle size and fuel calorific value, which are controlled by malfunction insertion and external parameter adjustment respectively. The primary airflow dynamics through the mill together with the grinding medium is also odeled.

• The wear of the mill liners is affected by malfunction insertion.Flame and flue-gas enthalpy is calculated on a first principles basis with the subsequent energy transferred to the water-walls and heater elements by radiation and convection.

The outward appearance of the lido CAD drawing and the Bailey CAD drawing will be the same.With this procedure for translation a very fast method is available to translate the huge amount of CAD drawings into the simulator format.A translation from simulator CAD format into Bailey CAD format is not available. Because of this a direct upload for CAD-drawings will not be possible.

• Control modifications can be done like this: modify at simulator any CAD drawing with LIDO and rectify and test it at simulator accordingly. When the modification of control was rectified at the simulator the modification at the unit will be done manually with the original CAD –editor of the plant. With this procedure modifications of the control can be tested at the simulator seriously and then applied to the unit.

• The C net is the net for internal communication of INF90 PCU’s . This net will physically not be available because the INF90 control is emulated. The data available on the C-net will be available at simulator at shared memory.Control running on PLC’s will be manually translated into simulator code. The procedure for modifications of the control will be the same as Bailey CAD drawings. Once a modification at simulator has proofed this change must be inserted in the unit manually.

Manjung Simulator System Capabilities

Schematic And Description Of Scenario Creation In The Simulator System

• The method of replay is to capture the operator input (Operator Action Log), and Reference Plant data (in the form of binary data and / or analogue data archived in the Reference Plant RTDS) for the output calculation of the Simulator System response.
  
• The binary data and / or analogue data archived in the Reference Plant RTDS shall be loaded from the Reference Plant via the communication link into the SEWS. Here, the data shall be duly converted for the Simulator System environment. Based on that converted data, the cause of the problem is expected to be analyzed by applying various Initial Conditions (ICs) or malfunctions that would bring about or lead to the scenario that happened in the Reference Plant. The final output of applying various ICs and malfunctions is combined with the converted log data (in the form of expert commands) and captured in a simulator scenario file. This simulator scenario file is then run on the Simulator System and compared with that event in the Reference Plant. If the result is unacceptable, a similar iterative process is required but using different Initial Conditions (ICs) or malfunctions.
  
• The Simulator System supports an "Input"-Replay. It is a feature where a replay always starts at a defined backtrack entry point and all the operator and instructor inputs which had been recorded during the previous replay recording will be inputted to the Simulator System. This means the models will calculate according each input and will produce the desired output to the hard panel soft simulation and displays. In the IS, the "Input"-Replay can be stopped and continued, repeated or put to “FREEZE”. In the latter case it is possible to continue with normal operation when going into “RUN” again.
