浅析220kV交流异网直流并列运行技术管理

Simple Analysis on DC Parallel Operation Techrology Management of 220kV AC Different Networks

为降低电解供电生产中电价成本问题,普遍使用交流异网直流并列运行方式,此种运行方式能够带来巨大经济利益的同时,也带来的很高的运行风险,所以供电的运行管理是否到位,是否切合实际至关重要。从防止非同期并列策略、稳流控制调整策略、异网间负荷控制策略三个方面分析交流异网直流并列运行方式的运行技术管理,切合实际制定相关措施和制度来保障铝电解交流异网直流并列运行方式的安全运行。

To reduce the elecytricity price cost of the electrolytric power suppply produetion, a DC parallel aperation way of AC different networks is widely used. This way can bring giant economic henefits, but bring running full of hazard. So, it is very important if the aperation management of power suply is corrent, or fits in with the needs. The paper ana- lyzed the operation technolgy management of the DC paralled running way of AC diferent networks from three aspects from avoiding non - synchronization parallel strategy, current - stable control strategy and ]aod contral strategy between the fiffenent networks and works out relevant measures and systems ensure safe operation of the DC paralled operation way of the aluminum electrolysis AC elifferent networks.
