Comprehensive energy fault diagnosis system and method based on comprehensive energy model

Abstract

The invention discloses a comprehensive energy fault diagnosis system and method based on a comprehensive energy model. The method comprises the following steps: constructing a comprehensive energy whole-network hydrothermal electrical station model; performing whole-network hydrothermal electrical station model data acquisition; longitudinally comparing various energy component data and general table data; transversely comparing various energy fault type data; enabling various energy fault measurement points to count and analyze the fault rate at regular time; carrying out comprehensive evaluation on the fault duration, carrying out comprehensive sorting according to the evaluation type and the evaluation fault level to obtain a fault point and a fault reason with the maximum influence, carrying out fault instruction distribution and alarm notification through a fault driving system, thereby reducing the fault duration, and realizing high-quality and reliable energy supply of a comprehensive energy system.

Description

technical field [0001] The invention relates to the technical field of comprehensive energy fault diagnosis, in particular to a comprehensive energy fault diagnosis system and method based on a comprehensive energy model. Background technique [0002] In order to reduce the duration of comprehensive energy failure and improve the comprehensive energy utilization rate, timely energy conversion, optimization control, and cut-off switch gates have become common means to improve the comprehensive energy utilization rate when the hydrothermal and electrical nodes of the whole network fail. Real-time online determination of comprehensive energy full-load operation to achieve safe and economical fault diagnosis and analysis schemes, focusing on the impact of the proportion of fault types on the operation of water, heat and electricity in the entire network, and evaluating the impact of fault duration and failure rate. The optimal fault regulation scheme is determined when the optim...

Problems solved by technology

[0004] In the absence of "longitudinal comparison of various energy component data and total table data, horizontal comparison of various energy failure type data, regular statistical analysis of failure rate and failure duration of various energy failure measurement points, and comprehensive evaluation" , there are deficiencies in the comprehensive fault energy diagnosis method in the prior art. For example, in the prior art, there is no longitudinal comparison between various energy component data and the total table data, resulting in the problem of incomplete statistics of fault types, and there is no comprehensive analysis of various energy fault types. The horizontal comparison of the data has caused the difficulty of finding the largest fault point, and there is no comprehensive evaluation, which has caused the failure of the failure cause analysis
