Abstract

The Start&Stop system allows Smart Transformers equipped with OLTC to increase efficiency dramatically whilst maintaining their capability to control voltage, thus improving the reactive power capability in renewable power plants to comply with grid codes. Experimental results show that by means of an innovative pre-insertion resistor, integrated in the OLTC, inrush current is fully mitigated even in the worst-case scenario, without the need of a complex circuit breaker controller.
