Programmed operation method for switching of intelligent bus interconnection interval

Abstract

The invention discloses a programmed operation method for switching of an intelligent bus interconnection interval, which comprises four programmed operation methods. The programmed operation method for switching an intelligent bus interconnection interval from operation to cold standby comprises the following steps that a logic controller sequentially transmits control commands of switching off a bus interconnection switch, switching off a first bus 1M knife switch of a bus interconnection interval and switching off a second bus 2M knife switch of the bus interconnection interval when the controller acquires information that the first bus 1M knife switch is not switched on, but the second bus 2M knife switch is switch on, besides the bus interconnection interval and a voltage transformer PT knife switch; and the logic controller sequentially transmits control commands of switching off the bus interconnection switch, switching off the second bus 2M knife switch of bus interconnection interval and switching off the first bus 1M knife switch of the bus interconnection switch when the controller acquires information that the second bus 2M knife switch is not switched on, but the first bus 1M knife switch is switch on, besides the bus interconnection interval and the PT knife switch. Therefore, the programmed operation for switching of the bus interconnection interval is ensured.

Description

technical field [0001] The invention belongs to the field of switching operation of substations in electric power systems, and relates to an intelligent programmed operation method for bus coupler interval operation in double-bus connection substations. It can also be used for intelligent programmatic operation of segment switch intervals. technical background [0002] Bus coupling (interconnection of double busbars) interval switching operation generally adopts the method of manual operation, and the operator executes it step by step according to the operation ticket. This method has a long operation time, and all logical judgments require manual intervention, which is prone to misjudgment and misjudgment. operations etc. [0003] The opening and closing switch sequence of the bus coupler bay switching operation will change with the change of the bus operation mode, and the same switching operation task will have multiple operating modes. In order to realize the programme...

Problems solved by technology

[0011] The purpose of the present invention is to provide an intelligent bus coupler interval switching program operation method to solve the problems of long time consumption, misjudgment and misoperation in conventional manual operation.

At the same time, the method provided by the present invention solves the problem that the existing programmed operation method cannot realize the one-button operation of bus coupler interval switching operation with multiple operation modes
