摘要
针对某厂供电系统电压不稳定,特别是冲压车间的末端母线,电压波动频繁,功率因数低的问题,设计了一种双向动态无功补偿装置,实现了电压的双向调整,克服了现有补偿方式存在调压不灵活、单向调压、控制开关受冲击、寿命短等缺点。在分析晶闸管最佳触发条件的基础上,采用光电零电压触发技术实现了电容器的无涌流投切。挂网运行结果证明了该补偿方法的有效性。
With the aim of mitigating instability of the power supply of a certain factory, especially improving the problem of voltage fluctuation and low power factor on the end of the pressing workshop, a bidirectional dynamic reactive power compensator can realize the bidirectional voltage regulation, which adopted the triggering technology of photoelectric zero voltage and brought elimination of inrush current and switching over-voltage.The compensation mode settled the previous drawbacks of inflexible and unidirectional voltage regulation,impulse impact on controlling switches and short lifespan.The experimental results show its validity.
