Power Loading Simulator Laboratory
- To train engineers in the techniques of economically controlling the system frequency of large power networks
- To study alternative operating procedures
- To investigate the range of characteristics and responses associated
with power generation
Parts of the Simulator:
- Main Simulator unit
- simulates an area of Load and Generation with system variables displayed in analogue form.
- six generators (steam, hydro, gas, base generation) including a pumped storage scheme
- load: by pre-recorded programme; available on tape
- additional grid network (for practising export and import)
- Load disconnection unit
- Tape recorder - providing load curve to the system
- Chart Recorder - taking hard copy output of system variables
- The simulator is 4 times faster than real-time. Three hour load curve is simulated in 45 minutes.
- Trainee engineers are given a load curve and characteristics of the system units. They prepare a load schedule in a response sheet such a way that:
- The frequency is maintained at 50 Hz
- The system units are operated economically
- Import/export commitments are met
- System generation and load at the start of the simulation time is set.
The simulator is transferred to programme mode. Tape drive feeds the load curve to the system. Trainees carry out the instructions as per the response sheet. Frequency is plotted. At the end of the simulation, total cost for the duration of the simulation is noted and compared with the standard cost.
