Background
The user side consumes 80% of the electric energy of the whole power grid, and the intelligent power management of the user side is of great significance to the user's reliability, safety and saving of electricity. The intelligent power service system is constructed to promote the multi-function energy meter intelligent energy management terminal and other equipment power management solutions to realize the two-ways positive interaction between the power grid and the user. The research contents that the client needs to solve mainly include: advanced meter, intelligent building, intelligent appliance, value-added service, customer power management system, demand-side management and so on. Acrel intelligent multi-function energy meter with an intelligent energy management system to help customers achieve real-time monitoring, high-precision electrical parameters acquisition, easy to install. It is suitable for the itemized measurement of electric energy in government organs and large public buildings.
Project Overview
Ireland customers use ADL200 to measure electrical parameters in their project. The customer installs Acrel ADL200 single-phase energy meter in the distribution cabinet. It is connected to the gateway through RS485 communication, and connected to the server through 4G, and the collected electrical parameter information is fed back to the management platform in real-time, so as to cooperate with the user to effectively monitor and manage the power consumption of the factory.
