Problems solved by technology

[0007] Disadvantage 1 of the existing technology: Traditional power system reliability prediction only considers the influence of disaster factors, but does not consider the reliability analysis under the action of multiple factors
[0008] Disadvantage 2 of the existing technology: Traditional power system reliability prediction only considers the influence of human factors, but does not consider the reliability analysis under the influence of multiple factors
[0009] Disadvantage 3 of existing technology: Traditional reliability often analyzes disaster factors as a whole, that is, considers the impact of disasters on equipment in the entire power system, but in actual situations, for the entire power system, transmission lines are affected Where hazards hit hardest, especially in the event of ice cover and high wind hazards
[0010] Disadvantage 4 of the existing technology: The traditional analysis of human factors in power systems often focuses on substations, but the most common operation in human factor operations is the opening and closing of circuit breakers, which has the greatest impact on transmission lines operation, so the reliability analysis of the power system considering human factors should take the transmission line as the main body to consider

Embodiment Construction

[0068] The present invention will be further described below in conjunction with drawings and embodiments.

[0069] Such as figure 1 Shown, embodiment of the present invention and its implementation process are as follows:

[0070] The first step: based on the IEEE RTS-79 standard system as the power system structure of the embodiment, such as figure 2 As shown, the original transmission line and other equipment parameters adopt the standard parameters of the IEEE RTS-79 standard system.

[0071] Among them, it is considered that transmission lines 11, 12 and 13 were affected by disasters and human-induced operations at the same time, and the remaining lines and equipment were not affected in any way.

[0072] The disaster factor considers the effect of icing, and the human factor operation considers the best situation, that is, there is no negative impact in the CREAM algorithm, and all positive or no-influence human factor operations.

[0073] Through the CREAM algorithm...

Abstract

The invention discloses a power system reliability evaluation algorithm comprehensively considering both disasters and human factors. The first step is as follows: the transmission lines of the powersystem are divided into four types, aiming at the transmission lines of different power systems and considering the influence of human operation and disaster on line reliability, the reliability of the whole power system is calculated by synthesizing the reliability of all kinds of transmission lines, including four kinds of transmission lines and other equipments of the power system, the reliability including reliability evaluation indexes such as probability of power shortage time and expectation value of power shortage. The invention refines the influence of the external factors on the power system to the influence on the transmission line, combines the influence of the disaster factors and the human factors, perfects the reliability analysis of the power system, and makes the calculation result more in line with the reality.

Description

technical field [0001] The invention belongs to the field of power system reliability evaluation considering multiple factors acting together, and in particular relates to a power system reliability evaluation algorithm that comprehensively considers disasters and human factors. Background technique [0002] Reliability technology was first developed from the aerospace industry and the electronics industry after the Second World War. The task of the power system is to provide users with continuous and qualified electrical energy. Due to various equipment in the power system, including primary equipment such as distributed power supplies, transformers, transmission lines, and circuit breakers, and their supporting secondary equipment, different types of faults will occur, which will affect the normal operation of the power system and the normal power supply to users. Power system failures will cause varying degrees of economic losses to power companies, users and certain link...
