摘要

To deal with reactive power disturbances in power grid introduced by speed and load changes of heavy DC hoist in operation, a reactive power predictive compensation strategy is proposed. After analysis of reactive power absorbed by the DC hoist in different operation stages, the work principle and the reactive power compensation flowchart and modification module are presented with reactive power compensation regulation based on fuzzy control. Finally, experiment results are given to demonstrate the effectiveness and robustness of the proposed strategy in reducing external and internal disturbances, with the power factor ranging from 0.95 to 0.98.
