Increase of continuity of power supply systems at territorially dispersed loads

Article preview

The article deals with the methodology of improving the reliability of power supply systems in conditions of geographically dispersed loads. The relevance of this issue is explained by the significant damage to mining enterprises due to power supply failures. The proposed methodology is based on the determination of the optimal number of electrical substations at mining enterprises and the connection of collector bus bars of different substations with the help of automatic operation of the reserve. The optimum number of electrical substations is determined using the method of potential functions. This method allows dividing consumers into groups and determining the center of electrical load in each group. Connection of different collector buses of substations increases the reliability of the power supply system of the enterprise as a whole. Calculation of reliability parameters for two variants of the power supply system, as well as their comparative analysis is carried out.

Determining the coordinates of the location and number of electrical substations at the industrial site of the mining enterprise

Article preview

Modern problems of designing power supply systems are considered. The method of constructing load maps using the method of potential functions and the method of determining the most profitable number of power substations using the target function are shown. The results of constructing the load chart with the use of software package MathCAD 2001 are presented. The optimal number of electric power substations is determined by the given target function of expenses. The method of choosing the variant with the optimal number of electric power substations and constructing two-dimensional image of potential function of receivers loads for this variant. Recommendations on the selection of optimal locations of electrical substations and the optimal allocation of electric consumers to individual electrical substations are given. The necessity of using modern software in the design of power supply systems was substantiated.
