As one of the clean energy sources, the installed capacity of wind farms has grown rapidly in recent years. Wind farms are divided into onshore wind farms and offshore wind farms. Generally, they are located in remote locations, with scattered installations and harsh environments. Therefore, wind farms need a remote monitoring system to facilitate operation and maintenance personnel to manage wind farm operations more efficiently.

With the continuous development of the social economy, the power system is moving towards the direction of high voltage and high capacity. New technologies and equipment of the power system emerge in an endless stream, and the power transmission capacity continues to improve.However, the high-voltage power load carried by high-voltage electrical equipment also makes its own temperature rise the culprit that threatens the stability of the power grid. Equipment temperature has become an important parameter for the stable operation of power transmission equipment in the current power grid.Based on the reasons for the temperature rise of high-voltage electrical equipment, this article analyzes the structure and application of the wireless temperature measurement system, analyzes the advantages and disadvantages of its application, and provides application examples to provide reference for the stable operation and development of our country's power system.

This article analysis the operation principle of hall current sensor, and application in battery management system.

NB/T 10861-2021 "design specification for the configuration of measuring devices in hydroelectric power plants" provides detailed requirements and guidance for the configuration of measuring devices in hydroelectric power plants.Measuring device is an important part of the operation monitoring of the hydroelectric power plant.The measurement of the hydroelectric power plant is mainly divided into electrical quantity measurement and non-electric quantity measurement.Electrical measurement refers to the measurement of electrical real-time parameters by means of electricity, including current, voltage, frequency, power factor, active/reactive power, active/reactive energy, etc.; non-electricity measurement refers to the use of transmitters to convert non-electricity Measure 4-20mA or 0-5V electrical signals, including temperature, speed, pressure, liquid level, opening, etc.This essay only discusses the measuring device and power consumption management system of the hydroelectric power plant according to the standard, and does not involve the microcomputer protection configuration of the hydroelectric power plant.
