Research on the Static Type of Dynamic Reactive Power Compensator of Mine Power Supply Network

研究了基于晶闸管控制和STEINMETZ理论的TCR型静止型动态滤波补偿装置(SVC)的基本工作原理,介绍了相应的硬件和软件结构,并将其应用到矿区实际供电电网进行无功补偿和滤波的实际测试实验。实验结果表明设计的SVC既实现无功功率的精确连续补偿,又可滤除高次谐波,从根本上改善矿区供电质量,取得了良好的效果。

The basic working principle of TCR static type of dynamic filter reactive power compensator based on thyristor control and STEINMETZ theory is studied, the framework of the compensator corresponding hardware and software is introduced, and the compensator is applied to actual testing experiments of reactive power compensation and filter to mining area power supply network. As a result, the test shows that the design of SVC can achieves the reactive power to be compensated accurately and continuously, at same time the high harmonics to be filtered, the quality of mining area power supply is radically improved, the effect is good.
