APP energy meter ADW300 forward and reverse energy metering

Description :

　　 The operation and maintenance of photovoltaic power plants are crucial to their power generation, including photovoltaic modules, inverters, related electrical circuits, step-up transformers, and grid connected cabinets. Data monitoring is a very important part of photovoltaic power plant operation and maintenance. Various data indicators of the photovoltaic power plant can be obtained in real time through the operation and maintenance management system, and the operating status and efficiency of the power plant can be judged through these data indicators. In terms of data monitoring, the following tests need to be conducted on photovoltaic power plants: firstly, real-time monitoring of parameters such as voltage, current, and power of the power plant is required to understand the real-time working status of the photovoltaic power plant. Secondly, it is necessary to monitor the environmental factors such as temperature, humidity, and solar irradiance of the photovoltaic power station to understand the operating environment of the power station. It is necessary to detect and analyze the cumulative power generation of photovoltaic power plants, the operation of components and inverters, etc., in order to take corresponding maintenance measures in a timely manner. GB/T 38946-2020 "Technical Specification for Centralized Operation and Maintenance of Distributed Photovoltaic Power Generation Systems" provides clear requirements for the operation and maintenance of distributed photovoltaic power stations, as well as the functions of centralized operation and maintenance main stations and sub stations

　　Introduction

　　In the context of dual carbon, the substitution of electricity for enterprise energy consumption will be a long-term trend. Therefore, a large number of new electrical equipment will be added within the enterprise. Improving the energy efficiency level of these equipment will reduce the total electricity consumption and help achieve the dual carbon goal as soon as possible.

　　Energy metering instruments that require multiple communication methods, support embedded and rail mounted installation, RS485, Lora, 4G and other data upload modes, and can achieve wiring free and power free construction.

　　Electric energy meters are installed at major distribution nodes, key energy consuming equipment, etc. They collect real-time electricity data, monitor the operation of the distribution system, and analyze the electricity data hourly, daily, and monthly. Combined with national and industry standards, they calculate the overall carbon emissions of the enterprise and provide basic data services for carbon neutrality.
