Summary: | The invention discloses a method and system for determining the capacity of a high-voltage shunt reactor. The method comprises the steps: determining the impedance of systems at two sides of a circuit, calculating the maximum overvoltage along a first line in a line-carrying no-load operation mode of the system with larger impedance, judging whether the maximum overvoltage is less than or equal toa set maximum overvoltage multiple, if not, calculating the maximum overvoltage along a second line, calculating the minimum value and the corresponding capacity distribution coefficient, and finallycalculating the capacities of the high-voltage shunt reactors at the head end and the tail end of the line. The system comprises a power system impedance determination module, a first judgment module, a first along-line maximum overvoltage calculation module, a second judgment module, a second along-line maximum overvoltage calculation module, a minimum calculation module and a high-voltage shuntreactor capacity calculati |
