Parametric study to evaluate the transient stability of an industrial power system
Service continuity is extremely importance for a petrochemical industrial plant, even during severe transient disturbances. A sudden stop in production may impose significant financial loss and require expensive cleanup. Within in an industrial power system, problems of transient stability in a synchronous motor have been identified. A parametric sensitivity analysis is used to analyze the transient stability response of the synchronous motor within the system. Power flow and short circuit analyses were used to check the steady state condition of the industrial system. Different excitation model representations and synchronous motors with different values of inertia constant H are used in the parametric analysis. The concept of nominal response for excitation systems is also described. The critical clearing time is used as a measure of stability of the system under the impact of both internal and external faults. Based on the results, recommendations to enhance the transient stability response of the system are offered.
