Abstract: 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-channels 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 application, value-added service, customer power management system, demand side management and so on. Acrel intelligent multi-function energy meter with 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.
1. Project Overview
Ireland customers use ADL200 to measure electrical parameters in his 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 communication, 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.
