Power grid frequency disturbance real-time monitoring system

Abstract

The invention provides a power grid frequency disturbance real-time monitoring system. The monitoring system comprises an upper computer and a monitoring terminal, wherein the monitoring terminal comprises a GPS positioning module, a GPRS communication module, a parameter storage module and a frequency detection module; the GPS positioning module and the frequency monitoring module are in signal connection with the GPRS communication module separately; and the upper computer is connected with the GPRS communication module through wireless communication and is used for receiving information ofthe frequency detection module and the GPS positioning module. The monitoring system has the beneficial effects that a power grid frequency disturbance real-time monitoring system terminal is installed in a power distribution room, so that real-time acquisition of the frequency of the power grid is realized, and a communication mode can be selected to realize data interaction with the upper computer monitoring system; in addition, the monitoring terminal also has an infrared learning function, and automatic temperature adjustment control is carried out on an air conditioner according to the temperature and humidity information of the power distribution room collected in real time; and meanwhile, a control command of the upper computer monitoring system can be received and a corresponding control operation can be performed.

Description

technical field [0001] The invention relates to the technical field of grid monitoring, in particular to a real-time monitoring system for grid frequency disturbance. Background technique [0002] Frequency is one of the most important parameters determining the performance of power systems, and its fast and accurate measurement is a basic requirement for the operation of power transmission systems. The market economy tends to require the power system to operate closer to the full load point, and offline measurement cannot predict a series of failures beyond the design parameters, so real-time continuous system dynamic monitoring is a better alternative. Previous research work has shown that a real-time, continuous, composite and unified frequency measurement and control system is needed. Due to the limitations of previous network and software technologies, it is difficult to achieve composite data acquisition and real-time integration, which reduces the accuracy of critical...
