Equipment selection. At the same time, the air compressor frequency conversion transformation also reduces the hidden waste of the enterprise.
At present, the cement plant power distribution network monitoring system and energy management system based on this implementation scheme have been successfully applied to actual cement engineering projects, providing changes to the ffiC61850 international standard for electrical safety and fault inquiries, maintenance, overhaul and diagnosis of cement plants. The power distribution monitoring platform has greatly increased the added value of the cement production line automation solution.
4 Conclusion With the increasing requirements for power supply safety and reliability of modern cement plants, the distribution of power distribution network monitoring systems and energy management systems for cement plants has become more and more part of cement plant engineering construction. Based on the ffiC61850 standard, an implementation scheme of power distribution monitoring engineering integrated with the ffiC61850 standard integrated in the DCS automation control system of cement plant is proposed. The successful application in concrete cement engineering projects shows that the scheme is practical. Moreover, the power distribution monitoring and energy management system constructed according to the scheme has advantages over the existing similar power distribution computer monitoring and management systems in terms of system performance, compatibility, implementation cost, and compliance with international power construction standards. The scheme can be extended to cement plants of the same scale to achieve seamless integration with the existing monitoring system of the plant, improve the automation management level of the same scale, and provide a strong accident safety analysis and diagnostic maintenance platform for the power and electricity of the cement plant. .
