Electric power system operation reliability-centered equipment importance evaluation method

Abstract

The invention relates to an electric power system operation reliability-centered equipment importance evaluation method. The method comprises the following steps of: 1, determining power transmission equipment needing to be evaluated; 2, selecting an element needing to be evaluated; 3, storing system initialization operating environment data; 4, restoring a system initialization operating environment; 5, evaluating an annual electric power system risk; 6, judging whether the number of specified operating times is reached or the calculation precision requirement is met, if the number of specified operating times is reached or the calculation precision requirement is met, entering a step 7, and if the number of specified operating times is not reached or the calculation precision requirement is not met, returning to the step 4; 7, counting system reliability and risk indicators; 8, judging whether all elements needing to be evaluated are evaluated, if all the elements needing to be evaluated are evaluated, entering a step 9, and if all the elements needing to be evaluated are not evaluated, returning to the step 2; and 9, counting element importance indicators, sequencing the element importance indicators, integrating corresponding economic indicators, safety indicators and environment indicators of a system after each equipment is launched, superimposing the economic indicators, the safety indicators and the environment indicators according to certain weight to obtain the corresponding overall indicators of the equipment, and sequencing the overall indicators.

Description

technical field [0001] The invention relates to an equipment importance evaluation method centering on the operation reliability of a power system. Background technique [0002] Currently, power systems are undergoing tremendous changes in terms of structure, operation and management, driven by technological advances and increasing customer expectations. Electric utilities are facing more and more uncertainties. Only by correctly operating the existing system and rationally planning the future system can the healthy development of the electric power industry be guaranteed. [0003] In the electricity market environment, in order to adapt to the changes in this environment, it is necessary to replace and repair old facilities in a timely manner, and continuously optimize the system configuration to improve the efficiency of transmission and distribution, improve the reliability of system operation, and reduce the cost of system operation . In order to achieve a better balan...

More importantly, if a component is out of operation due to a fault, it may cause overloading of other components in the grid, which may cause more serious accidents and even cause bad effects

Effective maintenance can reduce the probability of equipment failure, thereby avoiding various impacts and losses caused by accidents, and reducing operating costs; however, maintenance not only requires a large amount of investment, but more importantly, due to maintenance equipment Out of operation is likely to reduce the reliability of the entire power system operation, thereby increasing the risk of system operation during equipment maintenance
