基于双电源五角形接线的备自投控制策略

Control strategy of automatic bus transfer equipmentswith pentagonal wiring and dual sources

介绍了五角形接线备用电源自动投入装置的18种运行方式,提出了用“分解组合法”构成五角形接线备用电源自动投入装置的控制策略,并证明了该方法与“穷举法”构成五角形接线备用电源自动投入装置的运行方式相同。分析了这2种方法的优缺点,建议采用“分解组合法”构成五角形接线备用电源自动投入装置的控制策略,具有牵涉的环节少,动作逻辑和动作流程简单、方便,运行灵活,被分解的2部分既可组合运行,又可单独运行等优点。实际应用时,采用“分解组合法”实施某变电所五角形接线备用电源自动投入装置。

Eighteen operation patterns of automatic bus transfer equipments with pentagonal wiring and dual sources are introduced,which is constructed by using decomposition-combination method and proved same as those constructed by using exhaust algorithm. The advantages and disadvantages of these two methods are analyzed. The decomposition-combination method is recommended for its less taches,simple action logic and flow,and two operation modes of combination and seoarate. This method has been aoolied in oractice.
