Unit state analysis method and system based on network source network-related test

Abstract

The invention discloses a unit state analysis method and system based on a network source network-related test. The method comprises the following steps: acquiring a network-related test report sent by a power plant; extracting corresponding equipment parameters; inputting the equipment parameters into a correlation degree calculation formula, and calculating the correlation degree of the equipment parameters; classifying the equipment parameters according to an equipment parameter correlation degree calculation result to obtain a correlation parameter set; selecting information of a strong correlation parameter set from the correlation parameter set, and calculating a degradation degree value of the unit in combination with a test report; and determining a weight coefficient and a basic deduction value through the deterioration degree value, further calculating a state quantity deduction value, and performing final operation state judgment. The unit state can be updated in time according to a network-related test result of the network source unit, so that the management of the network source unit is more accurate and reasonable, and the working efficiency is improved. The unit with the abnormal running state can be discriminated in time, early warning is carried out in time when no fault occurs, implementation of rectification is supervised and urged, and the safety of a power grid is guaranteed.

Description

technical field

[0001] The invention relates to a unit state analysis method and system based on a network source-related network test, and belongs to the technical field of electric power systems. Background technique

[0002] The development of the power grid carries the mission of optimizing the allocation of energy resources, reducing energy consumption, effectively utilizing new energy, and promoting technological progress in emerging industries. It has become an important part of my country's energy strategy. As an important link in the construction of smart grid, with the large-scale application of power electronic devices and the operation of large-capacity high-voltage direct current transmission, the characteristics of "power electronics" and "strong direct and weak alternating current" in my country's power grid are becoming more and more obvious. On the one hand, the new characteristics of the grid directly affect the operation of the generator set. On the other...
