Wireless monitoring alarm control method for gas in transformer substation

Abstract

The invention discloses a wireless monitoring alarm control method for gas in a transformer substation. For the problems that some gas leakage in a present transformer substation can not be noticed easily, and real-time monitoring can not be achieved, an electric power cloud on-line monitoring terminal control system is independently researched and developed, the iterative algorithm is adopted in combination with the Gaussian mixture model to judge different types of gas leakage in a classified mode, and preventative measures are accurately taken in time to avoid accidents. According to the system, on-site terminal collectors are used for collecting the gas concentration around substation equipment in real time, terminals wirelessly transmit the data to substations in real time after data processing, and the substations carry out preliminary data summarization and send an information result obtained after processing to a control room master station and a mobile phone of a worker; the master station carries out further analysis on the mass data through cloud computing background processing and works out a gas state changing curve through fitting to ensure the accuracy of information prediction. The terminals, the substations, the master station and the mobile phone user can communicate and carry out control in time, communication among the weakest points of a fuel gas system is enhanced, and losses caused by communication delay are avoided.

Description

technical field [0001] The gas wireless monitoring and alarm control method based on the Gaussian mixture model and iterative algorithm is mainly used for online real-time monitoring and management inside the substation. Background technique [0002] It is understood that substation equipment is affected by natural forces such as environmental temperature changes, pollution, harmful gas corrosion, wind, rain and snow, coupled with improper construction of artificial equipment, resulting in gas leakage from time to time, and many gases are toxic, flammable and explosive. , if it is not found and dealt with in time, it may cause some accidents. However, the current electrical equipment generally adopts the "regular power outage preventive maintenance system", which has obvious defects such as high maintenance costs, missed accident reports, early reports or false reports, etc. Therefore, electric power and industrial and mining enterprises urgently require the realization of r...

Problems solved by technology

[0002] It is understood that substation equipment is affected by natural forces such as environmental temperature changes, pollution, harmful gas corrosion, wind, rain and snow, coupled with improper construction of artificial equipment, resulting in gas leakage from time to time, and many gases are toxic, flammable and explosive. , if not found and dealt with in time, it may cause some accidents

However, the current electrical equipment generally adopts the "regular power outage preventive maintenance system", which has obvious defects such as high maintenance costs, missed accident reports, early reports or false reports, etc. Therefore, electric power and industrial and mining enterprises urgently require the realization of regular or real-time online monitoring of electrical equipment operation The state, timely diagnosis of gas leakage faults and alarm, so as to realize the "condition maintenance system" based on the operation state maintenance and gradually replace the "regular power failure preventive maintenance system"
