Intelligent transformer station comprehensive monitoring system and realization method thereof

Abstract

The present invention discloses an intelligent transformer station comprehensive monitoring system and a realization method thereof. The intelligent transformer station comprehensive monitoring system comprises a transformer station monitoring system and a comprehensive control system, wherein the comprehensive control system comprises a frequency control subsystem, a voltage control subsystem, a load control subsystem, a small current grounding fault line selection subsystem, and a reactive-power control subsystem. The intelligent transformer station comprehensive monitoring system is characterized in that: the comprehensive control system and the transformer station monitoring system are connected through a communication network, the subsystems in the comprehensive control system achieve connection through computer cache, the transformer station monitoring system and the comprehensive control system are installed in a transformer station duty room. The intelligent transformer station comprehensive monitoring system of the present invention can replace various low-frequency low-voltage load-shedding devices, fault disconnection devices, main transformer overload cutoff devices, grounding fault line selection devices and reactive-power switching devices and corresponding systems thereof used in the prior art, thus repeated development of research and development personnel can be avoided, a development period can be shortened, and at the same time, construction cost of a power grid can be reduced, operation reliability of the power grid is effectively improved, and reasonable distribution of power grid load can be ensured.

Description

technical field [0001] The invention relates to an intelligent substation comprehensive monitoring system and its implementation method, in particular to an intelligent substation comprehensive monitoring system based on soft PLC and IEC61850 standards and its implementation method, belonging to the field of electrotechnical technology. Background technique [0002] At present, the State Grid Corporation of China proposes to build a strong smart grid, and smart substations are an important part of the smart grid. For the continuous development of smart substations, the advanced application functions of the smart substation monitoring system are required to be continuously enriched and strengthened. The "Technical Specifications for Relay Protection of Smart Substations" issued by the State Grid Corporation of China clearly states that functions such as standby automatic switching, overload switching function, and station domain control can be realized at the station control ...
