Development and application of distributed system for monitoring and control of electrical energy consumption for large consumers

Project includes investigation and analysis of all elements of electro-energetic system of large industrial complexes, including low and mid level transformer substations and intern distribution systems. Total installed power capacity in Copper Mining and Smelting Complex Bor, company which will be subject of analyses and implementation of project results, is about 500 MVA. Complex technological process of copper production considers spatially dislocated and time independent processes that all require huge consumption of electrical energy. At this point there is no possibility of simultaneous monitoring of electro-energetic system properties in all production units, which is extremely important for reduction of electrical energy costs, especially costs of the peak power. Implementation of the control and monitoring system will surely enable optimization of the production process and increase energetic efficiency. The main reduction of electrical energy costs is expected in decreasing the costs for the peak power, as well as compensation of reactive power, which are over 20% of overall costs. Hence, special attention will be given to optimization of the working regimes of all characteristic power consumers, in order to decrease peak power. It is expected that the project will ensure necessary conditions, and whenever is possible it will directly influence on optimization of the production process, with significant reduction of electrical energy costs.
