Small localised grid systems need to be protected from the effects of one or more generators tripping from the system. If no action is taken the system can suffer complete collapse if the other generators fail to pick up the load.
A load control system needs to know the individual loads connected and the maximum possible load generation. From this information a load shedding matrix can be developed to trip load from the system in the event of loss of generation. Load control can be programmed into the Turbine control system or supplied as a standalone system and typical functions include:
- Load Shedding
- Calculation of spinning reserve
- Automatic start-up and shutdown of generators
- Frequency control
- Load sharing between generators
TCL have installed load control systems on a number of Power Stations and offshore oil rigs to control system frequency and share load.
