Patent ID: 8610306

Claim:
A control system for a power plant including a medium voltage power line, the control system being configured to influence actual high voltage characteristics of a high voltage power line at a point-of-interconnection to a grid, the control system comprising: a medium voltage-compliant measurement system configured for connection with the medium voltage power line of the power plant, the medium voltage-compliant measurement system including at least one of: a voltage measurement device configured for measuring a voltage on the medium voltage power line, and a current measurement device configured for measuring a current on the medium voltage power line; and an evaluation unit connected to the medium voltage-compliant measurement system, the evaluation unit configured to: simulate high voltage characteristics of the high voltage power line comprising one or more of a voltage, current, power, reactive power or power factor, the high voltage characteristics being based on measurement values received from the medium voltage-compliant measurement system at the medium voltage power line by applying the measurement values from the medium voltage-compliant measurement system to a model of a transformer stored in a memory which transforms medium voltage on the medium voltage power line to high voltage on the high voltage power line, and generate a control signal based on the simulated high voltage characteristics in order to control the power plant for influencing the actual high voltage characteristics of the high voltage power line.
