Abstract:New type large capacity synchronous compensator can absorb or issue large amounts of reactive power. What’s more, the reactive power can be regulated fast and continuously. Due to this characteristic, it can provide large reactive power reserve for power grid, ameliorate the reactive power balance of the power grid and improve the stability, operation performance and benefit of the power grid effectively. It can also provide voltage support during power system failure. Its control strategy runs through the entire operation process, thus directly affecting its operation safety, reliability and economic benefits. The control principle of new type large capacity synchronous compensator and its model in under-excitation and over-excitation operation stages are analyzed to obtain the control strategy and focus in a project during the stages of start-up, operation and shutdown process.
