HVDC Data-based Optimal Frequency Control System and Frequency Controller Design Method and of LCC-HVDC System

摘要

The frequency controller design method of the current-type HVDC system of the present invention is a design method of a frequency control system of both current-type HVDC systems for controlling the frequency of a system connected to a prime mover generator, a rectifier and an inverter, respectively, The current-type HVDC system receiving data measured in a normal driving state of estimating an observer Markov variable and a system Markov variable from the collected data; forming a Henkel matrix using the system Markov variables; and constructing a data-based dynamic model for frequency control of the current-type HVDC system based on the Henkel matrix.
