Study on the Influence of Steady-state Voltage Regulation Schemes on Transient Reactive Power Supporting Capability
摘要
Abstract
Generator and static capacitors are important reactive power sources for steady-state voltage regulation. The generators supplying power to ultra high-voltage direct current (UHVDC) or supporting voltage for receiving end system are linked with the main network closely and can play important roles in steady voltage regulation. In view of the deficiency in the prevalent standpoint that reducing the generators’ steady-state reactive power output can increase transient reactive power reserve, the paper analyzed the influence of generator‘s steady-state operating conditions on transient reactive power output characteristics theoretically. Aimed to the generator and static capacitor combined system, the transient reactive supporting capability was defined with clear physical meaning and the optimized scheme of voltage regulation to enhance this capability is put forward. Simulation results obtained from test system and UHVDC/AC sending and receiving hybrid system show the transient voltage recovery characteristic can be improved by increasing the generator’s steady-state reactive power output.关键词
