STATISTICAL ESTIMATION OF MODE ENERGY CONSUMPTION THE POWERING CENTER OPENCAST MINE

In article presented basic results of analysis the load-graphs of main transformer substation. Displayed the diagram of basic electrical engineering equipment which works in the opencast mine. Showed that electro-technological equip-ment were working in random modes. The necessity of application the methods of mathematical statistics is for an estimation and determination the group loading. Showed algorithm of prognostication of the group loading, which based on normal distribution of the individual load-graphs. The algorithm consist of two global parts. The first part includes verification individual load electro-technological equipment for normal distribution. After verification simulating technological modes of equipment, than calculate standard dispersion, mathematical expectation and confidence limits. It is the second part of the algorithm. At the end of the article present conclusions. Developed algorithm prognostication of the group loading allows you to specify a group load, taking into account the connection diagram of the main equipment.
