The invention discloses a method and a device for evaluating power supply reliability of a power distribution network. The method comprises the following steps: firstly, defining and classifying medium-voltage users; generating a first user average power failure time measuring and calculating model and a second user average power failure time measuring and calculating model according to business indexes such as the proportion of power failure-to-power supply equivalent users, the proportion of non-power-supply-to-power-supply equivalent users, the stable value of the power failure times of the medium-voltage users, the stable value of the single power failure duration of the medium-voltage users and the like; and finally, according to planned power failure management level indexes and fault power failure management level indexes of the medium-voltage users, determining the average power failure time of the medium-voltage users by using the first user average power failure time measuring and calculating model or the second user average power failure time measuring and calculating model so as to evaluate the power supply reliability of the power distribution network. According to the method, multiple business indexes are combined, and the actual condition of the medium-voltage users is considered, so that the method is simple and practical, and has a relatively high reference value for actual business management of the power distribution network.
Description
technical field [0001] The present application relates to the technical field of power system data analysis, and in particular to a method and device for evaluating power supply reliability of a distribution network. Background technique [0002] A safe and reliable distribution network is an important guarantee for maintaining national economic development and people's living standards. The power supply reliability of the distribution network is a main indicator to measure the continuous power supply capability of the power supply system to medium-voltage users, and it is also an important technical indicator for power supply enterprises. The power supply reliability of the distribution network reflects the distribution network technology, equipment level and enterprise management level, and reflects the city's total economic development level. [0003] The domestic index for evaluating the reliability of distribution network power supply is usually the average power outag...
