智能型动态无功补偿及谐波扼制成套装置的开发与应用

Development and Application of Intelligent Dynamic Var-compensation and Harmonic-damp Equipment

新一代智能型动态无功补偿与谐波处理相结合的成套装置,配置以DSP+MCU的先进智能监控终端,基于可控硅与接触器并联的快速零电流投切,采用特殊工艺的电容、电抗器,根据配电系统负荷情况,实时动态零电流投切L-C滤波器,补偿cosΦ,同时扼制谐波、滤除谐波。

The novel intelligent dynamic equipment are combined by var-compensation and harmonic-processing together. It configures an advanced intelligent detect and control terminal with DSP ＋ MCU core. Based on quick zero-crossing current switching-on theory with controllable-silicon paralleling with contactor, the L-C filter sets which are produced using special technique, can achieve zero-crossing current switching-on in real-time according with various loads of distribution system. The equipment proposed can not only compensate eosФ but also damp or eliminate harmonics.
