Abstract

The embodiment of the invention provides a real-time database active power control system based on the combination of a centralized mode and a distributed mode. The system comprises a plurality of nodes, wherein each node stores the copy of a part of power grid real-time data of a real-time database which needs to be accessed by each node or needs to meet the preset requirements of the access performance, wherein the power grid real-time data, except for the copy of the power grid real-time data stored in each node, of the real-time database are distributed and stored in at least one part of the nodes according to preset configuration, and all the power grid real-time data stored in the nodes form a centralized and distributed combined real-time database. According to the system, the processing speed of the instruction of the active power control system can be effectively improved, and second-level processing of the original system can be improved to the millisecond-level processing speed; instruction lifting is accelerated, the high-speed response requirement of power station electric energy dispatching is met, and then stable operation of power station electric energy quality isguaranteed.

Description

technical field [0001] The invention relates to the technical field of active power control of a power grid, in particular to a real-time library active power control system based on a combination of centralized and distributed systems. Background technique [0002] The large-scale grid-connection of photovoltaic and wind farms has brought huge peak-shaving pressure to the grid dispatching system. The intermittent and random nature of photovoltaic and wind power generation has increased the instability of the grid system. The active power adjustment speed of existing photovoltaic and wind farm stations is slow. When the power system is disturbed and in an emergency state, photovoltaic and wind power generation cannot play its due role. The active power adjustment speed needs to be optimized and upgraded to give full play to the advantages of new energy power generation and make up for disadvantage. [0003] The active power control system realizes the collection of real-tim...
