Research On Reliability Of Low-voltage User Power Supply Based On User Response And Measurement Collection

Power reliability is an important index that reflects the management level of power enterprises,the safe operation of power system,and the power industry's satisfaction degree to the power demand of national economy.The supply reliability of low-voltage users is the direct reflection of the continuous,reliable supply and excellent service of the vast number of low-voltage users.With the increasing application and dependence of residents on electrical appliances,the tolerance of low-voltage users to power failure is getting lower and lower.Power supply enterprises need to calculate and analyze the reliability of low-voltage users,objectively reflect the current situation of enterprise power supply service,and formulate corresponding countermeasures to improve the power supply service.The study through literature understanding of low voltage user power supply reliability research status at home and abroad,through the theoretical research mastered,power reliability,the reliability of the power supply reliability research methods,through field investigation and analysis of low voltage power supply reliability of existing resources,measure and compare the user response to collect the advantages and disadvantages of two ways,combed the low-voltage users to blackout rules,finally based on the user response is clear and metering collection of low voltage user power supply reliability of the statistical method.This thesis based on the user response and measurement method of low voltage user power supply reliability,set up the administrative and cultural center of Tianjin area of low voltage user power supply reliability based data and operation data,the main index is calculated,analyzed the causes of the influence of low voltage user power supply reliability,targeted for the in distribution network automation in construction,reasonable arrangement plan,do not power operation,improve the efficiency of operations to repair,and to strengthen metering device operations,strengthen the low voltage user power supply reliability management,and other effective measures to improve the low voltage user power supply reliability,power supply service level of ascension.
