Balance of Plant Electrical Systems

The main task of the BoP-e is to supply the electrical energy from the generator out of the powerhouse into the electrical grid. This power train consists of medium voltage connections, switchgears and step-up transformers to match to the grid. High-voltage switchgears are the interface point between power plant and grid. In addition, numerous electrical energy systems and components are an integral part of the station supply of hydropower plants. The operation of a power plant requires electrical energy, e.g., to run motor-driven equipment like cooling or drainage pumps, cranes and electrical drives of valves.
