The key of the former system was designed according to the fact of china in the project. The draught-tension control system adopted a primary-secondary Variable Voltage and Variable Frequency control system instead of speed governing system of direct current; The on-line measurement control technique of pendency of cable was discussed, and the equipment for this technique was developed; the equipment also can adjust itself to kinds of cables and the situation where parameter of capacitance change; the method is new, and it can be applied several other facets. In the project we adopted a PLC-DCS combined hybrid control method with the merits of flexible configuration. Accurate measurement, coordinated control, reliable performance and convenient...
