摘要：

Unscheduled power flow is a major concern in interconnected power systems. Phase shifting transformers (PSTs) are one method used to control unscheduled power flow. This paper discusses the application, protection, commissioning, and initial operating history of two sets of parallel, 300-MVA, 345-kV, PSTs. The four Western Area Power Administration (WAPA) PSTs were energized in 1989 and are located in northwestern New Mexico in Shiprock and Waterflow Substations. The installations are unique because two PSTs, using a series no-load and load tap changer (LTC) design, are operated in parallel at each location.
