The system comprises a regional power grid incremental type multiple-target dynamic reactive power control subsystem, a strategy command issuing control interface, a reactive power control data interactive module, an incremental control module for considering the load fluctuation, a multiple-target layering reactive power control strategy generating module and an emergency response strategy module, wherein the reactive power control data interactive module is connected with a regional power grid energy management system by Ethernet; and the synchronous interaction of data is realized among the rest of modules by sharing a memory data pool. The system reads needed data directly from the existing regional power grid energy management system, thereby the hardware investment is saved by using the existing system; the incremental control module for considering the load fluctuation is effectively suitable for the real variation condition of the load of the power grid; and the multiple-target layering reactive power control strategy generating module effectively simplifies and calculates the complexity.

Description

technical field [0001] The invention relates to electrical engineering technology, in particular to an incremental multi-objective layered dynamic reactive power control method for a regional power grid. Background technique [0002] In the actual operation of the power system, it is one of the important tasks of the power management departments at all levels, especially the power dispatching centers at all levels, to realize the reasonable distribution of regional reactive power and the stable operation of voltage. At present, the data collection of the power control system is cumbersome, and the data management ability is poor; most of the voltage and reactive power control is based on the sampling data at a certain moment of the power grid, which is conducive to the simplification of the calculation process and the improvement of control efficiency. However, since the load is always changing, the reactive power control based on the data collected in a single time section ...

At present, the data collection of the power control system is cumbersome, and the data management ability is poor; most of the voltage and reactive power control is based on the sampling data at a certain moment of the power grid, which is conducive to the simplification of the calculation process and the improvement of control efficiency. However, since the load is always changing, the reactive power control based on the data collected in a single time section cannot well meet the actual operation needs. The increase of losses, as well as the frequent actions of capacitor switches and main transformer taps; Changes will greatly increase the complexity of reactive power control
