Overvoltage on-line monitoring system for power system

Abstract

The invention discloses an overvoltage on-line monitoring system for a power system. The overvoltage on-line monitoring system comprises an equipment voltage acquisition module, a communication moduleand an on-line monitoring platform; the equipment voltage acquisition module is wirelessly connected with the online monitoring platform through the communication module; the equipment voltage acquisition module is used for acquiring voltage data of field working equipment and summarizing and sorting the data; and the online monitoring platform is used for receiving the voltage data acquired by the equipment voltage acquisition module, classifying the voltage data and displaying the voltage data in a form of a table. According to the invention, the voltage information acquisition unit and thecurrent information acquisition unit respectively acquire voltage and current information of an equipment field; the voltage and current information is gathered into the data arrangement unit and then sent to the on-line monitoring platform, and a table is generated through the table making unit according to the data type and displayed in the display unit for workers to check.

Description

technical field [0001] The invention relates to the technical field of voltage monitoring, in particular to an online overvoltage monitoring system of a power system. Background technique [0002] Voltage, also known as potential difference or potential difference, is a physical quantity that measures the energy difference generated by a unit charge in an electrostatic field due to different potentials. , the direction of the voltage is defined as the direction from high potential to low potential. The international unit system for voltage is volts (referred to as volts), and commonly used units include millivolts, microvolts, and kilovolts. This concept is similar to "water pressure" caused by high and low water levels. It should be pointed out that the term "voltage" is generally only used in circuits, while "potential difference" and "potential difference" are generally used in all electrical phenomena. [0003] During the daily operation of the equipment, the power su...

AI Technical Summary

Problems solved by technology

[0003] During the daily operation of the equipment, the power supply capacity of the power supply (transformer) is too small, the low-voltage power supply line is too long, and the cross-section of the low-voltage power supply line is too small, etc., which will cause the voltage fluctuation of the equipment and affect the normal operation of the equipment. The various voltages of the equipment are effectively monitored, and it is difficult to ensure the long-term stability of the equipment voltage
