Abstract: In response to the common problems encountered by large energy equipment manufacturing enterprises in the energy management process, Dongfang Boiler has built a "four unified and feasible" energy intelligent management platform, established a five level energy monitoring system, carried out energy monitoring statistics, energy consumption anomaly diagnosis, and refined energy management of public and auxiliary systems and key production processes. It has achieved monitoring of 8 energy media (working fluids) such as water, electricity, and natural gas, covering more than 1000 meter terminals and parameter management of more than 2000 measurement points, significantly reducing energy consumption per 10000 yuan and achieving significant results.
