voltage monitoring method and system based on an AVC system operation environment

Abstract

The invention provides a voltage monitoring method and system based on an AVC system operation environment. Relating to the technical field of power systems, According to the invention, the power supply voltage can be continuously monitored; the monitored real-time data and all data in the monitoring time range can be displayed on the nixie tube; data information of the voltage monitor is inquired; the defects in the prior art are overcome; Design reasonableness, a wireless communication mode is combined with a wired communication mode; Statistical data of the voltage monitors installed at allmonitoring points of a power grid are transmitted to the voltage monitoring data acquisition master station system. Data of voltage, power factors and the like are uploaded to an AVC system, data sources of control and assessment are unified, statistics of monitoring data of the voltage monitor is greatly facilitated, and meanwhile the reliability and the stability of the voltage monitor in the system operation environment are improved.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a voltage monitoring method and system based on an AVC system operating environment. Background technique [0002] The voltage monitor is a statistical voltage monitor that continuously monitors and counts the voltage deviation caused by the slow change of the normal operating state of the power system. With monitoring, analysis, memory, query, parameter setting and other functions. [0003] During the data acquisition and transmission process of the existing voltage monitoring system, due to factors such as automation system and network communication, data abnormalities (including dead data and slow refresh) will occur, resulting in a decrease in the reliability of the telemetry data that the AVC system relies on. At the same time, the management department is Strengthen the monitoring and assessment of voltage qualification rate, and independently deploy voltage monitori...

Problems solved by technology

[0003] During the data acquisition and transmission process of the existing voltage monitoring system, due to factors such as automation system and network communication, data abnormalities (including dead data and slow refresh) will occur, resulting in a decrease in the reliability of the telemetry data that the AVC system relies on. At the same time, the management department is Strengthen the monitoring and assessment of voltage qualification rate, and independently deploy voltage monitoring devices and background systems. Due to the limitations of deployment methods and transmission conditions, intensive statistics and analysis of data cannot be carried out. The AVC system for voltage regulation and control and the voltage monitoring system for statistical assessment Inconsistent and out-of-synchronization of voltage data leads to disjointed assessment and adjustment, which brings difficulties to voltage operation control and management. Therefore, we propose a voltage monitoring method and system based on the AVC system operating environment
