A computerized evaluation method for power user's reliability demand in market environment

Abstract

The invention relates to an analyzing and processing method of the reliability requirement of a power consumer, in particular to a computer assessment method of the reliability requirement of the power consumer in a marketing environment. The invention is combined with the requirements of power supply enterprises to research the method for assessing the power supply reliability requirement of any power supply region. The method comprises the following steps: providing key consumer characteristic information influencing the reliability requirement through analyzing the damage degree of power failure to consumers in different industries; and providing a region power supply reliability requirement grade quantitative evaluation method based on the consumer characteristic information through applying a fuzzy decision method. The invention aims to compare and measure the serious damage and loss degrees of power failure objectively according to regional consumer constitution, and develop the power supply reliability requirement more scientifically. The analyzing and processing method provides a certain reference for power distribution network planning and reliability lifting scheme decision.

Description

technical field [0001] The invention relates to a method for analyzing and processing reliability requirements of power users, in particular to a computer evaluation method for reliability requirements of power users in a market environment. Background technique [0002] The reliability of user power supply is an important technical index in the production management of power supply enterprises. However, the improvement of power supply reliability is often accompanied by the increase of grid investment and the decrease of normal utilization rate of power transmission and distribution equipment. Reliability and economy are usually contradictory, and one-sided emphasis on either will lead to improper technical handling. The user's annual average power outage time and power outage times are two key indicators in the technical processing of power supply reliability. The degree of harm of power outages to users is closely related to the type of users. [0003] First of all, ele...

Problems solved by technology

Power outages in these industries often also cause extremely serious losses such as damage to heavy processing equipment, explosions, etc.

However, due to the large power consumption of these heavy-duty manufacturing enterprises, they all use dedicated substations and dedicated transmission lines to supply power from 110kV and above voltage levels, and are equipped with self-provided power plants and other measures to ensure their power supply, and are not included in the power supply reliability of medium and low voltage distribution networks. Statistical range

[0008] 2) For light industrial users, short-term power outages generally only lead to production stop losses during power outages, and single-batch and waste product losses caused by sudden power outages

[0017] The power failure of the above-mentioned users may pose a threat to personal safety, and the degree of harm is more serious than pure economic loss

However, because the power supply of my country's subway operation is generally supplied by dedicated lines and dedicated substations of the rail transit system, the impact of the subway system may not be considered in the reliability assessment of the public power distribution system
