站间备自投逻辑控制策略研究

Research on Logic Control Strategy of Standby Automatic Switching between Stations

常规备自投的应用要求变电站内具有开环点开关,对于电力系统中常见的串供形式的电网架构,由于闭环运行的变电站内无开环点开关导致无法使用常规备自投。针对常规备自投应用的局限性,提出了站间备自投逻辑控制策略,并说明了具体的实现方式,据此可以极大提高系统供电的可靠性,对其它电网结构的备自投逻辑控制策略的研究也具有良好的借鉴意义。

The application of conventional standby automatic switching requires an open-loop point switch in the substation.For the common series power grid architecture in the power system,the conventional standby automatic switching cannot be used because there is no open-loop point switch in the closed-loop operation substation.Aiming at the limitations of conventional backup automatic switching applications,a logic control strategy for backup automatic switching between stations is proposed,and the specific implementation method is explained.Using the logic control strategy for backup automatic switching between stations can greatly improve the reliability of system power supply.The research on the logic control strategy of the power grid structure of standby automatic switching also has good reference significance.
