The control of the equipment of power quality dynamic compensation is importent factor that influence the performance of the equipment 电能质量动态补偿装置,作为装配于配电网中,用于谐波抑制和无功补偿的新型装置,得到了广泛的重视。
At present , the research on compensating reactive power using static compensation device is one of the most active areas in power electronics subject 利用静止无功补偿装置实现动态无功功率补偿的研究是目前电力电子学科中比较活跃的研究领域之一。
It is no use inputting the tune wave filter and the compensate instruments with the power factor because the little pollution of the tune wave and the lower power factor 对电网谐波污染小、输人功率因数高。不必采用输人谐波滤波器和功率因数补偿装置。
The principle of voltage adjustment and power factor improvement in capacitor were analyzed , and the choossing approach was introduced 摘要本文分析了电容器作为无功补偿装置在电压调整和功率因数提高方面的作用原理，同时介绍了具体应用中电容器的选择方法。
This paper also points out the influence of harmonics to the compensation system , and the protect measurement in the condition of high harmonics on the power net 在本文中，还介绍了电网谐波对补偿装置的影响，以及装置在电网谐波含量超标时采取的保护措施。
The intent is to find out the capacitance and place of installing the dynamic reactive power compensators in sichuan power system in order to provide the base for system layout and design 研究的目的是找出动态无功补偿装置在四川电网中的装设容量和地点，为系统的规划设计提供依据。
The testing hall is equipped with 1 , 800kv impulse voltage generator , 2 , 000 4 , 000kw 50 100hz frequency conversion generator group and 30 , 000kvar capicitor compensation device and so on 试验大厅安装有2400kv冲击电压发生器2000 4000kw 50 100hz变频发电机组及30000kvar电容补偿装置等。
Intelligent static phase generator ( ispg ) is a kind of equipment of compensating reactive power , which technically designed for large and medium - sized wound - type electromotor to save energy and reduce wastage 智能型静止进相器是专为大中型绕线式电机节能降耗设计的无功功率就地补偿装置。
An intelligent device was designed for var compensation . the device took the 80c196kb singlechip micro - controller as main control chip , took reactive power as control target and took voltage as restricting condition 设计了一套以80c196kb为核心的智能无功补偿装置，该装置以无功功率最小作为控制策略，以电压作为约束条件。
Abstract : the paper has introduced the building technology of the replacement of compensation device and the contact wire in the course of the existing railway - speed - increasing catenary device rebuilding , as a reference to the builder 文摘:介绍了既有线提速接触网设备改造中更换补偿装置及接触导线施工技术，供从事施工人员参考。
