Abstract

The invention relates to the technical field of electrical power systems, and puts forward an electrical power system and a design method. The electrical power system comprises electrical power equipment subjected to standardized design. The design method for the electrical power system comprises the following steps that: connecting the neutral point of the electrical power system with a ground terminal through a resistor; and according to the altitude of the electrical power system, providing an overvoltage protector, wherein the overvoltage protector is used for protecting the electrical power equipment. By use of the electrical power system provided by the invention, on one hand, an insulation level can be met, and on the other hand, the system is simple in operation and maintenance andlow in cost.

Description

technical field [0001] The present invention relates to the technical field of power systems, in particular to a power system and a design method. Background technique [0002] A power system includes a variety of electrical equipment, such as circuit breakers. In order to ensure the stable operation of the power system, the insulation capacity of each electrical equipment needs to be considered during the design process of the power system. Each electrical equipment has insulation withstand voltage parameters. In the design of the power system, it is necessary to select the appropriate electrical equipment according to the insulation level of the power system. However, the insulation withstand voltage parameter of electrical equipment characterizes the insulation capability of electrical equipment at an altitude of 1000m. When the altitude increases, due to factors such as thin air and low air pressure, the insulation strength of the air will weaken, and the external insu...
