METHOD FOR BUILDING SYNTHESIS LOAD MODEL CONSIDERING LOW VOLTAGE RELEASE FEATURE OF LOAD

摘要

A method for building a synthesis load model considering a low voltage release feature of load. The synthesis load model comprises a static load model and a motor load model. The method comprises the following steps: step 1: building a static load model according to a low voltage release feature of static load; step 2: building a motor load model according to a low voltage release feature of motor load; and step 3: determining active power and reactive power output by a synthesis load model. The model overcomes the defect that a traditional dynamic load model cannot describe the low voltage release feature of load, and improves the accuracy and reliability of power system simulation calculation.
