RELIABILITY EFFICIENCY OF ELECTRIC POWER SYSTEMS

Abstract

The article deals with the general issues of definition and ensures power systems performance indicators, taking into account the required security of supply on the part of consumers and businesses generating opportunities and related electricity providers. The main traditional and advanced methods to ensure the reliability and evaluation of its effectiveness are provided. The authors formulate criteria for evaluating the effectiveness of reliability from the perspective of manufacturers, suppliers, consumers and others involved in the generation, transportation and transformation of electricity. The article points to specific tasks associated with reliability in supplying power system sites related to the schemes of internal and external power supply, and the possibility of theoretical analysis of internal power supply schemes, taking into account regulatory requirements on reliability of power supply mains of different categories, different costs to ensure the required reliability. The reliability is defined taking into account the reliability of elements, structural solutions and the redundancy, control in the circuit of the internal power supply, and the level of reliability provided by the electricity supply company.
