Abstract

The invention belongs to the field of abnormal state identification and misoperation prevention of a power secondary system, and in particular relates to a secondary system abnormality identification and misoperation prevention system and method in a substation multi-association scene. Based on the standardization of substation information description and standardization of operation process, deploy and configure comprehensive error prevention functions and anti-error strategies in devices at all levels of the secondary system of the device, station server, and dispatching server. Information modeling and identification of the operating status of subsystems. At the same time, before the primary and secondary operation of the substation, according to the topology of the power grid and the operation setting status of the secondary device, whether the pre-performance operation will cause system abnormality or misoperation, if it causes system abnormality or misoperation, actively send an alarm through analysis, prohibit or Prompt, and prevent and remedy misoperations and abnormal operating states in the system, so as to realize positive intervention in on-site operation and maintenance work.

Description

technical field [0001] The invention belongs to the field of abnormal state identification and misoperation prevention of a power secondary system, and particularly relates to a method for identifying abnormal states and misoperations of substations through standardized model information description in the multi-association scenario of substations, and avoiding the occurrence of malignant accidents based on the execution of anti-misoperation strategies. Anti-error system and method. Background technique [0002] The operation reliability of the power system is the basis and one of the most important technical indicators for the realization of the power production and operation functions. The misoperation in the substation and the abnormal operation of the system may lead to the occurrence of vicious accidents, resulting in the loss of personnel, power grid and equipment. At present, there is an anti-mistake locking system for primary equipment in substations, also known as "...
