摘要
冶金行业大容量电弧炉的应用给电网带来了严重的电压闪变和谐波污染问题,静止无功补偿装置(SVC)是抑制系统电压闪变和谐波的重要工具之一。文章针对电弧炉的静止无功补偿装置的安装容量过大的缺点,主电路采用滤波器和电容器组相结合的方式,结合滤波器最小安装容量法,能够有效地减小静止无功补偿装置的安装容量,提高了经济效益。利用MATLAB\PSB模块对SVC进行仿真,仿真结果证明了设计方法正确、可靠。
A serious harmonic pollution is brought by a large number of applications of nonlinear load,Static Var Compensator（SVC） is one of the most important tools to suppression system voltage flicker and harmonic wave.An in-depth research is carried out in this paper that how the connecting of the discharge device impact the safety and relay protection in the SVC and how to design the SVC,to adopt the main circuit with filter and capacitor combination,and combinate the filters installed minimum capacity,to effectively reduce the SVC installed capacity and improve the economic efficiency.The MATLAB／PSB module is used to simulate for SVC,the simulation results show that the design method is correct and reliable.
