与大电网松散联系的6kV供电系统无功补偿

Reactive Power Compensation for 6 kV Power Supply System Connected Loosely with Power Grid

通过现场大量实测数据，对一个含有自备发电厂，又与大电网有松散联系的６ｋＶ独立供电系统的无功补偿方案进行了分析、讨论和模拟计算，使本供电系统的功率因数，不论是在最大负荷（冬季出现），还是在最小负荷（夏季出现），都能保持在０．９以上，满足了入网要求。

Based on a large amount of load records measured on site,the reactive powercompensation for a 6 kV independent supply system containing a self-supply power plant andconnected loosely with power grid is analysed,discussed,and simulated in order to make thepower factor remain more than 0.9,either in the highest load or in the lowest one and,thus,meet the demand of grid coupling.This paper is valuable for practical reference in connectionwith similar stipply system.
