The fact that industrial production requires a high level of efficiency and safety justifies the need for a stable operation of power system.

Compared with the information room, the industrial application site is plagued by problems, such as poor power grid, complex production site, strong interference the production equipment has. The control system has become more and more complex, which is in line with the increasingly automatic industrial production. Moreover, control systems, such as DCS, PLC and FCS, are control management equipment frequently used in industrial production and has strict requirement on the quality of power supply. Therefore, more and more manufacturers of DCS, PLC and FCS have adopted dual power input.

The complex power system of the plant requires assurance on the safety, reliability, stability and intelligence of power supply and distribution throughout the plant, so as to ensure an effective control on the monitoring, control, protection of the power system, as well as electricity and electrical management under both normal and accidental circumstances. The Scheme is applied to the automation of the power system in the whole factory. The function design includes monitoring, control and protection, etc.

Informatization and intelligence of the energy efficiency management of all energies (water, electricity, natural gas, steam, compressed air, etc.) in whole-factory level and even enterprise-level have an important meaning of the energy saving and efficiency increase for enterprises. The solution is applicable for all public power subsystems of the whole factory and the comprehensive monitoring and control management of the whole factory environment.

With the integration of monitoring, control and management of all the utility power and plants in the whole factory for the facility management & control at the same time, improvement in the energy efficiency statistic and management efficiency and consequent conservation in time and human cost has become an increasingly prominent demand. This Scheme is applicable to the facility management system in the whole factory and the integrated supervision & control management of the plant environment.
