Embodiment Construction

[0081] The method for decomposing the reliability index of the regional distribution network described in this embodiment is applied to an example of index decomposition in 2010 of a power supply bureau of a certain city.

[0082] A city's power supply bureau has 33 grassroots units (4 distribution departments and 29 township power supply stations) under its jurisdiction. As of the beginning of 2010, there were 586 urban feeder lines and 6,228 urban households; 2,772 rural feeder lines and 46,647 rural households.

[0083] In 2009, the average power outage time of global urban users in a city was 10.79 hours / household (power supply reliability rate RS-1 was 99.88%), and the global average power outage time of rural users was 20.20 hours / household (power supply reliability rate RS-1 was 99.77%).

[0084] In 2010, the higher authorities ordered that the reliability index of a power supply bureau in a certain city should be controlled within: the average power outage time of user...

Abstract

The invention discloses a method for resolving a reliability index of a regional distribution network. The method mainly comprises the steps of resolving a planned power failure index; and resolving a random power failure index in each grass-roots unit, and combining resolved results of the planned power failure index and the random power failure index. According to the method for resolving a yearly reliability index of a regional power supply bureau to subordinate functional departments / grass-roots production units to the regional power supply bureau, the index issuing has scientific reasonability, public transparency and implementation feasibility. The practice shows that the reliability index resolving method model is accurate, reasonable, simple and practicable and is conveniently popularized and applied to the regional power supply bureau.

Description

technical field [0001] The invention belongs to the field of power supply reliability, and in particular relates to a method for decomposing reliability indexes of regional distribution networks. Background technique [0002] Power system reliability refers to the measurement of the power system's ability to supply power and energy to power users uninterruptedly according to acceptable quality standards and required quantities. [0003] The distribution network is the link that directly faces the users in the power system, and has the most direct impact on the quality and reliability of the power supply of the users. The power supply capacity and reliability of the entire power system to users are reflected through the distribution network, and the reliability index of the distribution network is actually a concentrated expression of the structure, operating characteristics and reliability level of the entire power system. [0004] At present, long-term research has been ca...
