Real-time early warning system and method based on primary electrical system of power plant

Abstract

The invention provides a real-time early warning system and method based on a primary electrical system of a power plant, and a signal processing module is used for receiving abnormal data in a treatment plant-level information monitoring system, enabling the processed abnormal data to correspond to an electrical operation mode simulation diagram in a one-to-one manner, marking an abnormal region, and sending the abnormal region to field staff in an actual power plant abnormal area through multiple alarm devices and terminal display screens so that real-time monitoring, accurate positioning and rapid alarm of the power plant abnormal electrical operation mode are achieved, the processing efficiency of the field staff is improved, the problem that the field staff discriminates an abnormal circuit through paper files can be solved, meanwhile, major accidents caused by neglecting data abnormity due to human factors can be greatly reduced, and the safe and economic operation and management level of the thermal power plant can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of safety and economic operation monitoring of thermal power plants, and in particular relates to a real-time early warning system and method based on the primary electrical system of the power plant. Background technique [0002] The real-time operation mode of the electrical system is an important content that the on-duty supervisor and operating personnel need to master. Previously, in order to make it easier for the duty chief to fully understand the electrical method, the printed electrical diagram was generally used. When the duty chief handed over a shift, he selected and marked the status of the switch and knife in the operation management software. [0003] However, for power plants with very complicated electrical operation methods, the electronic version of the diagram is limited by the size of the CRT screen, so it can only be very vague. Moreover, the method of state change marking makes the st...

[0003] However, for power plants with very complex electrical operation methods, the electronic version of the diagram is limited by the size of the CRT screen, so it can only be very vague

Moreover, the method of state change marking makes the state of the switch not very clear and can be changed at will after the shift, which leads to the fact that this method map can neither reflect the real-time operation mode of the electrical system in real time, nor is it convenient; at the same time, the complex electrical system of the power plant Operation mode, in the case of changes in the operation mode or emergency abnormal conditions, the on-site staff cannot accurately grasp the actual equipment status of the production site, and cannot immediately deal with abnormal problems or make adjustment arrangements for the operation mode according to the actual operation mode.
