IoT 4G electricity meter ADW300 carbon neutrality

Description :

　　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.

　　9、 Application scenarios

　　The issue of power quality is receiving increasing attention and has become one of the research hotspots in the power system. On the one hand, with the development of science and technology and the widespread application of various complex electrical equipment, a large part of these devices are very sensitive to power quality; On the other hand, the continuous expansion of the power system scale and the rapid increase in electricity demand have led to very unstable power quality. The main purpose of analyzing power quality is to determine the type and range of power signal disturbances, and to make reasonable adjustments and compensations to the corresponding disturbance sources. Therefore, the key to improving and enhancing power quality lies in timely and accurate acquisition of information from various disturbance signal sources.

　　Power quality monitoring, including three aspects of imbalance, harmonics, and power factor, is presented in the form of a vector diagram to show the three-phase imbalance. When there is an imbalance in three aspects or a low power factor, an alarm will be generated, triggering various reminders such as APP, mobile SMS, email, DingTalk, voice, etc.

　　The inverter of distributed photovoltaic projects needs to have the ability to quickly detect islands and immediately disconnect from the power grid upon detecting islands. Its anti island solution should be coordinated with relay protection configuration, safety automatic devices, and low voltage detection devices, and match the time. The anti islanding detection strategy of the inverter should comply with the corresponding regulations of the State Grid

　　The inverter is equipped with reverse protection, short circuit protection, low voltage ride through, islanding protection, overheating protection, overload protection, grounding protection, etc. High voltage switchgear is equipped with measurement and control protection devices, including overcurrent protection and zero sequence overcurrent protection. The measurement and control protection device uploads all information to the photovoltaic local monitoring system through communication.

　　The photovoltaic power station of this project can quickly disconnect from the grid connection and stop supplying power to the grid in case of faults or abnormal operating conditions, without affecting the normal operation of the existing system.
