摘要
投切电容器组容易产生过电压,长期过电压会缩短电容器的使用寿命,影响其他设备的正常运行。因此对不加装保护装置三相系统简化电路进行分析,在分析电容器组过电压阻尼装置原理的基础上对未投入阻尼装置系统电路进行MATLAB仿真,仿真得出合闸角与过电压的关系。
Switching capacitor banks is easy to produce overvoltage. Long-term overvoltage will shorten the service life of capacitors and affect the normal operation of other equipments. In this paper, the simplified circuit of three-phase system without protective devices is analyzed. On the basis of analyzing the principle of overvoltage damper for capacitor banks, the undamped system is put forward. The whole circuit is simulated by MATLAB, and the relationship between closing angle and overvoltage is obtained by simulation.
