Arrangement for decentralized supply of regenerative energy performs voltage regulation at combination point for controlled improvement of quality of electrical supply

摘要

The arrangement regulates the voltage at a combination point for controlled electrical supply quality improvement. The arrangement for supplying power and the voltage regulator are in one unit. The regulator has arrangements for specifying a desired voltage spectrum at the combination point, diagnosing the state of the supply network and determining demand values of harmonics and/or a fundamental frequency reactive power to be compensated. The arrangement performs voltage regulation at a combination point for controlled improvement of the quality of the electrical supply. The arrangement for supplying power and the voltage regulator are contained in one unit. The regulator (17,20) has arrangements for specifying a desired voltage spectrum at the combination point, for diagnosing the state of the supply network and for determining demand values of harmonics to be compensated and/or a fundamental frequency reactive power to be compensated. Independent claims are also included for the following: a current converter.
