Sensitivity analysis of synchronous generators for real-time simulations

Abstract

The purpose of this paper is to investigate the compatibility of generator models in PSS/E (Power System Simulator for Engineering), EMTP (ElectroMagnetic Transient Program), and Hypersim, a platform used for the real time modeling and simulation of power systems. The paper introduces a methodology for the comparison of generator models by performing sensitivity analysis of power system responses to generator parameter changes. The three platforms produce identical outputs in steady state but different responses in dynamic studies, and the methodology outlines steps for finding and changing generator parameters in one platform to best match the response achieved by another platform. A standard IEEE 14 bus system is analyzed under normal steady state and dynamic conditions and under faulted conditions.
