1 Overview In today's world, fossil fuels such as coal and petroleum frequently suffer from urgency and environmental pollution has become increasingly severe. As the most promising renewable energy source, solar energy is increasingly favored by people because of its unlimited reserves, universal existence, cleanliness of use, and practical economy. The vigorous development of the photovoltaic industry and the active development of solar energy have attracted unprecedented attention on a global scale and have become an important part of the sustainable development strategy of various countries. The photovoltaic industry is also called the solar cell industry, which is an industry that uses solar-grade semiconductor electronic devices to absorb solar radiation energy and convert it into electrical energy. Photovoltaic power plants are mainly composed of photovoltaic arrays, combiner boxes, low-voltage DC cabinets, inverter cabinets, AC low-voltage cabinets, step-up transformers, etc. The resulting high-voltage AC power is directly incorporated into the power grid. In response to the need for power parameter detection at each step, Ancorui launched the AGF Series PV Collector, PZ Series DC Detector, and ACR Series Power Quality Analyzers, which are used in combiner boxes, DC cabinets, and AC cabinets, respectively. Through the Acrel-3000 V8.0 photovoltaic power monitoring system to achieve centralized monitoring of the background. Acrel-3000 V8.0 photovoltaic power generation monitoring system is a software platform developed by Shanghai Ankerui Electric Co., Ltd. for solar power generation systems. It can be used for solar arrays, combiner boxes, inverters, and AC/DC distribution cabinets in solar photovoltaic power plants. , Sun tracking control systems and other equipment for real-time monitoring and control, through a variety of styles of charts and data to quickly grasp the operation of the plant, its friendly user interface, powerful analysis capabilities, complete fault alarm to ensure that the solar photovoltaic power generation system Fully reliable and stable operation. 2 PV power plant power monitoring meter AGF series solar collector collecting device is specially used in intelligent photovoltaic combiner box to monitor the operation status of the solar panel in photovoltaic arrays, photocell current measurement, lightning arrester status acquisition in the combiner box, DC breaker status acquisition, and relay contact output. There are sensor interfaces such as wind speed, temperature, and irradiator. The device has an RS485 interface to upload the measured and collected data and device status. PZ series DC detection instrument is designed for DC screen, solar power supply, telecommunication base station and other applications. This series of instruments can measure voltage, current, power, forward and reverse power in DC system. Can be used for local display, but also with industrial control equipment, computer connections, form a measurement and control system. The meter can have RS-485 communication interface and adopts Modbus-RTU protocol; it can have analog output, relay alarm output and digital input/output. According to different requirements, the ratio, alarm, communication, and digital output are set and controlled through the instrument panel keys.
