Embodiment Construction

[0021] For the process shown in Figure 1-2, for the sake of easy expression, the remote control logic of the outgoing line switch of the 110kV substation is used as a simple example: when it is necessary to perform remote control operation on the outgoing line switch KG1 (1001), the line needs to be judged before remote control The handcart switch SC1 must be in the "closed" state, and the grounding knife switch JD1 must be in the "open" state. Therefore, first we use PS-Logic to edit the 1001KG.log file, in which the corresponding switch operation logic is as follows:

[0022] KG1==1&&SC1==1&&JD1==0

[0023] Only when the logic is satisfied, the remote control of the switch can be exported, otherwise it will be blocked.

[0024] After editing 1001KG.log, use PS-GCC to compile 1001KG.log and check the syntax. If there is a syntax error in the file, the line number and type of the error can be prompted, otherwise the compilation result will be saved in binary mode in 1001KG.b...

Abstract

The present invention relates to a logic locking device to prevent software error in a telemechanical installation and two innovation functions to realize program operation in a whole transformer substation based on the logic locking device belonging to the technical field of power system automation. In detail, the present invention fulfills a whole set of functions ranging from logic definition, logic compilation download, logic execution and logic locking by defining PS-Logic high-level language and corresponding PS-GCC compilation tool to conduct logic judgment to remote control, remote regulating, fixed value operation and other operation commands dispatched at remote end and lock operating featuring logic error, thus ensuring safety and reliability of remote operation. In addition, the present invention describes a group of operation functions through PS-Logic language based on complex program control to realize program operation in the whole transformer substation through remote control of the telemechanical installation, thus improving daily operation convenience of the transformer substation and greatly reducing error operation due to personal negligence.

Description

technical field [0001] The present invention relates to the field of power system automation. Specifically, the present invention is aimed at the specific application of telecontrol communication devices in power systems. Through the design of a series of software algorithms and functional modules, the telecontrol device realizes the anti-mistake logic locking function and The program-based operation function of the whole station improves the reliability and economy of the power system operation. The invention belongs to the technical field of power system factory station automation. Background technique [0002] At present, the operation of primary equipment such as switches and knife switches in power plants and substations is often carried out in two ways. One is to remotely control through the local monitoring background, and the other is to issue operation commands from remote dispatchers. for remote control. The current monitoring background has a relatively complete...
