摘要：

This paper presents the influences of the large motor starting and the large rolling mill operation on the isolated integrated steel cogeneration facility by executing the transient stability analysis. The system configuration of the steel facility will be introduced first. Furthermore, the proper mathematical models and the accurate parameters of the co-generators, excitation systems and governor systems are investigated in detail. Both the static and dynamic load models are applied in this paper. To reduce the starting current of large motors, the conventional step-down voltage method by adjusting the suitable tap position of the autotransformer and the constant magnetic flux control method by using the VVVF inverter are considered in the computer simulations. Also, the system voltage and frequency fluctuations due to the operation of the rolling mill will be observed and investigated carefully to verify the isolated cogeneration can be operated well and safely.
