Abstract | The invention relates to a method for discriminating requirements of an ultra-high voltage (UHV) line steady-state overvoltage device, which is based on the lossless transmission line theory. According to the lossless transmission line theory, the voltage relationship and the current relationship between any two points on a line can be analyzed as long as distribution parameters of wires are known. By using the characteristic, the method analyzes the voltage distribution situations when a power system with a UHV idle line operates, comprehensively considers the parameters, the lengths and thehigh-resistance configurations of UHV wires, and judges whether steady-state overvoltage problems occur in the UHV line and whether a steady-state overvoltage device needs to be configured. Traditional discriminating methods completely use power system simulation software to conduct large amounts of verbose simulations, however, the discriminating method of the invention overcomes the problems, has the characteristics of |
