Automatic analysis system for wind power plant reactive power regulation capacity based on WAMS dynamic data

The invention discloses an automatic analysis system for the wind power plant reactive power regulation capacity based on WAMS dynamic data. The system comprises a real-time monitor module, an evaluation and examination module, a safety pre-warning module and an accident analysis module. The real-time monitor module monitors changes between active power and reactive power of wind power equipment in real time. The evaluation and examination module counts the three-phase current unbalance degree, operation conditions and dynamic reactive power response capacity of a reactive compensation device, counts voltage deviation, variation in voltage, the three-phase voltage unbalance degree, frequency and active power changes, and counts the reactive power supporting capacity when in high-low voltage ride-through and low voltage ride-through of a wind turbine generator. The safety pre-warning module analyzes the voltage stability index and high-low voltage ride-through events. The accident analysis module analyzes the active power recovery situation of offline events. According to the technical scheme, the automatic analysis system is used for achieving the purpose of estimating reactive power regulation operation capacity in an intelligent power grid dispatching technical support system, and an assisting tool and a convenience means are provided for power grid dispatching operation personnel to locate draught fan offline reasons rapidly.
