Operation Situation Analysis and Improvement Measure Study for Reactive Voltage Control System in Wind Farm

The control strategy of reactive power and voltage, communication between systems and the performance of the single device will affect the performance of the reactive and voltage control of the field station. On the basis of one million kilowatts of wind power base in the past three years the actual operation data and field test data, firstly analyzes the status of the wind farm without the system voltage and reactive power control system, introduces the current voltage and reactive power control system architecture and common control strategy; secondly from the station of reactive power and voltage control of the process, clarify the key factor effect of terminal voltage and reactive power control performance; the final form of the promotion of wind farm reactive voltage control performance and operation level of the measures, which is verified.
