无功补偿装置继电保护整定值的研究

Study on Relay Protection Settings for Reactive Power Compensation Installations

近几年变电站无功补偿装置事故频繁发生 ,很多是产品质量以外的原因。譬如 :未按照《并联电容器装置设计规范》要求设计、施工质量差、继电保护定值不合理等 ,均会造成无功补偿装置事故的发生。本文仅从继电保护定值分析无功补偿装置的事故 。

In recent years, failures of reactive power compensation installations occur frequently ,but many failures are not caused by product quality. For example, not in accordance with 'Design specifications of Shunt Capacitor', poor quality of construction, and irrational relay settings often cause failures of the reactive power compensation installation. This article focuses only on failures caused by relay settings of reactive power compensation installations in order to put emphasis on this problem.
