This paper introduces a convenient and efficient way to model a CPS-SPWM based MMC control system with 4 defined controllers, which are power control block, averaging and balancing control block, carrier and firing pulses block. Equivalent control subroutines are designed in the defined controller, which can change the labor of duplication of large amount of control components to simply change the...Show More
This paper proposes a real-time hybrid transient simulation platform combining the real-time digital simulator (RTDS) and a transient stability analysis (TSA) program to simulate large scale AC/DC hybrid systems. To improve the accuracy of simulation results, a frequency dependent network equivalent (FDNE) is implemented in this simulation platform. And a latest GTFPGA card is used to realize the ...Show More
The DC line fault which occurred on the pole 2 of Guizhou-Guangdong HVDC of China South Grid company on January 15th, 2007 is simulated successfully by using the HVDC simulation model of RTDS that is essentially identical with the actual control and protection system. We use the transient wave calculation procedure in LabVIEW to compare the similarity indices of the simulation results and the faul...Show More
HVDC Light has so much outstanding performance that it has been highly appreciated by power industry all over the world.After brief introduction and analysis to the principle and technique characteristics, the control modes and control system of HVDC Light, a discussion about applying HVDC Light to CSG is presented in this paper. Two models in EMTDC are proposed which illustrate the potential appl...Show More
