Regional power grid power outage information studying and judging system and method based on power grid power outage characteristics

Abstract

The invention discloses a regional power grid power outage information studying and judging system and method based on power grid power outage characteristics. The system comprises an information collecting module, a line power outage judging module, a date platform file receiving and storing module, a power outage information optimizing module and a client side inquiring module. According to the regional power grid power outage information studying and judging system and method, fault tripping and operation power outage are accurately recognized by combining overhaul application ticket information declared by countries, through the logic relation of switch deflection time and according to the characteristics of fault tripping and operation power outage, invalid power outage information generated by remote signaling jitter is filtered out, the recognition rate of fault tripping and operation power outage is effectively increased, the false alarm rate caused by false sending of signals is decreased, and the accurate rate of the regional power grid power outage information is greatly increased. The regional power grid power outage information studying and judging system and method has important significance on improving the power supply reliability of regional power grids, supervising and executing orderly power consumption measures and starting emergent responses in time, and meanwhile a promoting role is played in improving the normalization level of counties calling EMS data and models.

Description

technical field [0001] The invention relates to the technical field of power system automation, in particular to a system and method for researching and judging regional power grid power outage information based on power grid power outage characteristics. Background technique [0002] Power supply reliability refers to the ability of the power supply system to continuously supply power. It is an important indicator for evaluating the power quality of the power supply system. It reflects the degree to which the power industry meets the power demand of the national economy. It has become one of the standards for measuring the degree of economic development of a country; reliable power supply The reliability can be measured by the following series of indicators: the average power outage time of users, the average number of power outages of users, and the equivalent hours of system power outages. The accuracy of power outage events directly determines the accuracy of reliability...

Problems solved by technology

[0004] At present, there are three main methods for provincial power companies to obtain information on power outages of 10-110kV lines in the province: (1) The dispatching system makes statistics and reports step by step. Statistics and summarization have poor real-time performance and disperse the energy of the dispatcher to deal with the accident; (2) the marketing department complains about the telephone traffic to 95598. The disadvantage of this method is that it needs to accumulate a certain amount of traffic to indirectly detect the cause of the power outage Lines, the acquisition of information is not comprehensive, direct, and rapid, and it is only suitable as an auxiliary means of monitoring power outage information; (3) Operating the monitoring system of monitoring institutions, the disadvantage of this method is that the information and models accessed by the system are incomplete and cannot meet the actual situation. need
