【Abstract】 This paper is the continuation of the paper published in last issue, the software of the STDBUS-based microcomputer control system for HVDC system is introuced. Based upon the multi-CPU modularized hardware, the software of this system is divided into several parts. Each part performs a special task in cooperation with the corresponding hardware board. The PD-PID computation method is used in the constant current and constant voltage adjusters and it’s a success. The results of dynamic imitating tests show that this control system has the charateristics of high reliabilty, flexibility and high speed.更多还原
