【Abstract】 DC control Power System, which plays an important role of traction power substation , is expected to be with the characters of higher reliability, automation, precision, smaller figure and maintenance-free while the technique and management of electric railway develop rapidly. The development of DC control power system described in this paper is oriented to the Baoji-Chengdu electric railway-engineering project. A DC control Power System, which is based on PLC, HF switch rectifier and valve control seal battery is described in the paper. The designing and researching of DC control Power System of a typical traction power substation such as system designing, HMI and program designing, elements choice, panel configuration etc. are carried out. Automation control and management of the system are introduced in the paper as well as PLC, touch screen and collecting, inspecting device. The system has obtained user’s reputation with its advanced techniques, good characters, automation and efficiency. The research of this paper is as below:(1) Based on a real electric railway engineering, a new DC control power system is proposed and developed.(2) The design of automation control unit and management unit of DC control power system is carried out.(3) The design and programme of HMI-touch screen is carried out.(4) The problem is discussed on connecting between management unit of DC control power system and field bus of the substation automation system.更多还原
