Problems solved by technology

The whole process requires pre-rehearsal and is limited by the five-defense system. Once the five-defense system makes an error, it will cause a serious accident
Due to the need for manual participation in the entire switching process, and the influence of the performance of five anti-device devices such as computer keys and electronic locking devices, the risk of accidents will inevitably increase
[0003] With the continuous increase of the capacity of the substation, the continuous improvement of the voltage level, th

Abstract

The invention discloses a system for completing sequential control by intelligent one-key operation. The system consists of an operator station of a station monitor and control layer, intelligent equipment of a bay layer, and an intelligent interface of a process layer; and the control process comprises that: a sequential control instruction is selected manually on the operator station of the station monitor and control layer through a mouse or a key, and is transmitted to a device of the bay layer through an Ethernet; after receiving a sequential control command of a background machine, the intelligent equipment of the bay layer independently performs sequential control, and adopts GOOSE mechanism-based logic interlock judgment to realize misoperation prevention; and a network of the process layer and the intelligent interface of the process layer perform information interaction of a tripping command and a position state, and the interactive mechanism is based on a GOOSE mechanism. The system has clear hierarchies; and the GOOSE mechanism ensures quick and reliable information transmission, and the sequential control ensures high efficiency and reliability of switching operation.

Description

technical field [0001] The invention belongs to the technical field of power system automation, and in particular relates to an intelligent one-key operation sequence control system, in particular to a sequence control system used in a fully digital substation of a power system to perform switching operations on primary equipment at intervals. Background technique [0002] At present, in order to prevent accidents caused by wrong switching operation in the power system, electrical secondary anti-mistake blocking measures and five-proof systems are widely used to ensure the safe operation of the power system. The electrical secondary error prevention measure is to use the auxiliary contacts of the circuit breaker and the knife switch in the secondary operation circuit, and connect the interlocking unit in series in the operation circuit to achieve error prevention, but the wiring is complicated and depends on the reliability of the entire secondary operation circuit. When the...
