Intelligent transformer and distribution comprehensive monitoring system

Abstract

The invention discloses an intelligent transformer and distribution comprehensive monitoring system, which comprises a main control machine, a front end detecting device and an HMI (human machine interface) connected with the main control machine, wherein the input end of the main control machine is connected with the front end detecting device, the front end detecting device comprises a comprehensive intelligent meter, a microcomputer protection test and control device and a harmonic analyzer, a serial port server and a switch are also connected between the front end detecting device and the main control machine, and the output end of the main control machine is connected with a data processing module, a liquid crystal display, a warning device and a printer. The intelligent transformer and distribution comprehensive monitoring system has the advantages that the structure is simple, the design is reasonable, the realization is convenient, the use and the operation are convenient and fast, the voltage condition of a transformer substation can be monitored in real time, data of various kinds of detecting equipment can be transmitted through the data processing module, the data transmission reliability is high, in addition, the data loss is avoided, the control reliability is high, the work stability is high, the service life is long, the practicability is high, the use effect is good, and the popularization and the use are convenient.

Description

technical field [0001] The invention relates to the technical field of power monitoring systems, in particular to an intelligent integrated monitoring system for power transformation and distribution. Background technique [0002] The continuous development and safe and stable operation of the power system have brought huge power benefits to the national economy and social development. Once a natural or man-made fault occurs in the power system and cannot be controlled in time, the system will lose stability and cause damage to the main equipment. The disintegration of substations caused large-scale power outages, which brought serious consequences to the system and the society. Substation monitoring system protection is an important means to ensure the safe and stable operation of the power system. However, the existing substation monitoring systems only use control and protection units without monitoring. It does not have the function of control, monitoring, measurement an...

[0002] The continuous development and safe and stable operation of the power system have brought huge power benefits to the national economy and social development. Once a natural or man-made fault occurs in the power system and cannot be controlled in time, the system will lose stability and cause damage to the main equipment. The disintegration of substations caused large-scale power outages, which brought serious consequences to the system and the society. Substation monitoring system protection is an important means to ensure the safe and stable operation of the power system. However, the existing substation monitoring systems only use control and protection units without monitoring. It does not have the function of control, monitoring, measurement and alarm. Since the location of the substation is far away, the on-duty personnel need to have corresponding professional skills, and they can deal with problems in time when problems are found. On-duty status and low safety and reliability
