Voltage stability load parameter determination from field tests on BC Hydro's system

This paper reports on the findings of an EPRI project exploring the determination of load characteristic for voltage stability analysis from field tests. The results of the extensive load tests performed on the BC Hydro system are summarized. Based on the these results, important factors affecting test design and load parameter estimation are identified and typical load parameters are determined. Finally, a simple and effective load test procedure is proposed for future tests.
