Line predictive transformation system and its working method based on power grid dispatching error prevention system

Abstract

The invention discloses a line predicting and reforming system based on a power grid dispatching anti-error system and a working method of the line predicting and reforming system and relates to a system for predicating and changing line conditions at the intermediate and later stages of line reforming and a working method of the system. The line predicting and reforming system and the working method thereof can be used for realizing predication by misoperation-preventive locking and operating recommendation of whole-network equipment as well as reforming renewal. The line predicting and reforming system comprises a graphical interface module, a model data processing module, a layer mapping module and a misoperation-preventive locking control and operation recommendation module. The working method comprises the following step of (1) initializing; (2) analyzing; (3) establishing and mapping layers; (4) carrying out recommendation judgment; (5) giving an operation recommendation; (6) carrying out renewal judgment of drawings; (7) substituting an actual area chart; and (8) finishing predicting and reforming. The system disclosed by the invention can be used for furthest eradicating sequence error in power-on / power-off coordinated operation and has important significance on guarantee of safety production of power grid reforming. The power grid predicting anti-error system automatically adapts to topological structure change, and drawings for network reforming are maintained in advance, so that the use workload is greatly reduced.

Description

technical field [0001] The invention relates to a power grid prediction and error prevention system and its working method, in particular to a system and its working method for predicting and modifying the line status in the middle and later stages of line reconstruction. Background technique [0002] In the power system, in order to prevent misuse of electrical equipment, it is necessary to perform a "five-prevention" blocking check on the current operation. The usual "five preventions" refer to the prevention of five misoperation accidents that often occur in the switching operation of the power system, that is, the isolating switch with load, the circuit breaker, the load switch, the contactor, the grounding switch Close the circuit breaker and load switch when it is in the closed position, and close the grounding switch by mistake when it is live, and enter the charged interval by mistake. [0003] In order to improve the reliability of power supply in the power system,...

Problems solved by technology

[0004] The current error prevention system can only realize the operation lock between existing equipment under the actual network structure, and cannot realize the operation lock and operation prompt between equipment during and after the power grid transformation
