1. control system that is used to control the heterogeneous electric furnace that is coupled to polyphase source, described control system comprises:

  • Variable reactor, each that is coupling in heterogeneous electric furnace are mutually and between the corresponding phase of polyphase source;

    Monitoring device is coupled to each variable reactor, be used to monitor electric furnace each phase operating characteristic and determine whether that the operating characteristic of at least one phase departs from corresponding set point;

    Control device, be coupled to each variable reactor and described monitoring device, the set point that is used for the phase that is coupled to according to it is provided with the value of each variable reactor, described control device is configured, operating characteristic with at least one phase of carrying out in response to described monitoring device departs from determining of corresponding set point, based on all operating characteristic that go up mutually the value of each variable reactor is set, to realize corresponding set point.
