摘　　要：为减小同步辐射装置负荷所致配电网络电压波动,采用晶闸管投切电容器无功补偿装置(以交流过零型固体继电器为开关)进行无功补偿。该装置以负荷侧无功电流幅值IQM为电力电容的投切判据;借助MATLAB仿真工具SIMULINK仿真补偿后的配电网络,获得IQM进而求得该网络无功补偿所需的电容量,用晶闸管投切最终网络得到所需无功功率补偿,电压的波动值控制在允许范围内。The reactive power compensation is required to reduce the voltage fluctuation of distribution network re sulted from the surge load of Synchronous Radiation Facility power supply system,. The Thyristor Switching Capacitor（TSC） reactive power compensation facility is introduced, which uses alternating zero-voltage-crossing Solid State Relay（SSR） as its switch, and adopts the var current amplitude of the load as the criterion to switch on or off the capacitor. The vat current amplitude of the load is obtained through a simulation tool in simulink of MATLAB, and the value of on-or-off-switch capacitor is acquired, which will realize the reactive power compensation in this network, Because the network reactive power is compensated, the voltage fluctuation value of the distribution network can be controlled in the permitted standard.
