摘要

As the utility industry in the United States continues to move forward with deregulation, financial and market forces are demanding a more optimal and profitable operation of the power system with respect to generation, transmission, and distribution. In addition, with the recent concerns at the US government level over transmission system reliability, including comments from the Federal Energy Regulatory Commission (FERC), more efficient utilization and control of existing networks are required. Electricity is increasingly being considered as a commodity in the United States. As a result, transmission systems are being pushed closer to their stability and thermal limits, while the focus on the quality of power delivered is greater than ever. Now, more than at any other time in the history of the electric utility industry, the application of advanced control technologies are critical for the reliable and secure operation of power systems. Power electronics based equipment, such as Flexible AC Transmission Systems (FACTS) and Custom Power technologies, which implement voltage source inverter (VSI) based technology concepts, constitute some of the most suitable and proven technical advancements to address the new operating challenges being presented today. These advancements are based on the high-performance capability of power electronics equipment to rapidly respond to dynamic system events, increase power transfer limits, and improve the quality of power delivered. The benefits of FACTS and Custom Power technologies have become widely recognized within the electric power industry, and each year more projects are being implemented throughout the United States and other parts of North America by both the utility and industrial sectors for VSI-based systems. This paper summarizes two recent applications of VSI-based technology in the United States; one which addresses power transmission system operating issues and is currently under construction (the Vermont Electric Power Company's Essex Substation +133/-41 MVA, 115 kV STATCOM Project), and the other which focuses on distribution level power quality improvement and was completed earlier this year (the Seattle Iron & Metals Corporation's 5 MVA, 4.16 kV D-STATCOM Project). Brief descriptions of these two applications are provided herein. It is anticipated that an increasing number of similar applications will be required throughout the United States, North America, and other parts of the world in the very near future, to further provide solutions for the enhancement of power system operation, performance, and control.
