Rukhlov A. The decision method of the power supply emergency reservation of coal mines

The thesis is devoted to the questions of decline ground of consumable and declared of the power supply emergency reservation of coal mines by smoothing of the group electric loading diagrams and decline of electro-receivers power of emergency reservation at presence of such possibility. The analysis of positions of the operating directive documents regulating of power supply emergency reservation of enterprises is executed, and also "Acts of ecological, emergency and technological reservation of user power supply" and operating method of these loading decision, which testifies to the improper attributing of electro-receivers to emergency reservation and its computation. The specific features of coal mines on comparison from other industrial enterprises are exposed, consisting in possibility to lose the booty mechanized complexes as a result of co-operation of lateral breeds of coal layer with hydro support movable fasten. This results in the necessity of attributing to the emergency reservation electro-receivers of machines and machineries participating in the upgrade of coal face lines and delivery of coal on surface. The modeling algorithms of the individual electric loading diagrams are developed on the period of action of power supply emergency reservation for the pumping installation and for process on the upgrade of coal face lines. The imitation model of forming of the group electric loading diagrams and decision of power supply emergency reservation of coal mines for two characteristic periods of power supply limitation is developed.
