Reactive Voltage Control of UHV AC/DC Jiangsu Power System
With the fast expansion of UHV AC/DC system in China,it has been generally acknowledged that the receiving power grid terminal should expand the scale of outside power input.This paper analyzes the development of Jiangsu power grid planning and reactive voltage operation,probes into the importance of researching reactive voltage control,and discusses the static reactive voltage control strategy and reactive power compensation scheme in the context of UHV AC/DC power system.The grid dynamic reactive voltage margin was simulated and analyzed ; the voltage stability was calibrated under critical faults.To improve the voltage stability margin level of power grid near UHV DC,the installation of dynamic reactive power compensation device and other appropriate measures are proposed,and the effectiveness is verified by simulation results.
