In the application of today’s power distribution facilities, power distribution safety is of the utmost importance. The application of the Acrel-3000 power management system introduced in this article in the commercial plaza project can realize real-time monitoring of the power consumption of the power supply and distribution circuit, not only can display the circuit The power consumption status also has the function of network communication, which can form an electric energy management system with serial server, computer, etc. The system realizes the analysis and processing of the collected data, real-time display of the operating status of each power distribution circuit in the power distribution room, pop-up alarm dialogs, voice prompts for load overruns, and generates various energy reports, analysis curves, graphics, etc., It is convenient for remote meter reading, analysis and research of electric energy. The system is safe, reliable and stable in operation. It provides a safe and reliable basis for the commercial plaza project to solve electricity problems, and has achieved good corporate benefits.
