VOLTAGE REGULATION OF A UTILITY POWER NETWORK

摘要

Power compensation is provided from a power compensation device (30) to a utility power network carrying a nominal voltage. The power compensation device has a steady-state power delivery characteristic. The power compensation is provided by detecting a change of a predetermined magnitude in the nominal voltage on the utility power network and controlling the power compensation device to deliver, for a first period of time and in response t o the detected change in the nominal voltage, reactive power to the utility power network. The power compensation device is controlled to deliver, for a secon d period of time following the first period of time, reactive power to the utility power network at a level that is a factor N(N$m(g)1) greater than the steady-state power delivery characteristic of the power compensation device.
