The invention relates to a synchronous data acquisition method applied to grid stability control. The synchronous data acquisition method comprises a sampling step, a full-wave effective value calculation step, a fundamental wave parameter calculation step, an alignment step and an uploading step, and can upload a sampling value, a full-wave effective value and a fundamental wave parameter in a time section, having the sampling value, the full-wave effective value and the fundamental wave parameter and being closest to a data uploading moment, as uploading data to a main station at the data uploading moment. By adopting the synchronous data acquisition method applied to grid stability control, the highly-reliable safety and stability control strategy can be achieved, and the data acquisition moments of acquisition points can be determined by the safety and stability control main station, thus the system state can be analyzed on the same time section, and the operational requirements ofthe wide-range safety and stability control system is satisfied.
Description
technical field [0001] The present disclosure relates to the field of power system security and stability control, in particular to a synchronous data acquisition method applied to power grid stability control. Background technique [0002] In the power system, the safety and stability control system is an important line of defense to ensure the stable operation of the power grid. With the development of interconnected power grids, the role of centralized decision-making safety and stability control systems is becoming more and more important in wide-area power grids, and the application of high-reliability safety and stability control strategies is also increasing. higher requirements. [0003] However, for the existing centralized decision-making safety and stability control system, the safety and stability control sub-stations usually only send active power to the safety and stability control master station, the amount of information is seriously insufficient and there i...
