Abstract :
THE BONNEVILLE Power Administration (BPA) transmission network serves the load areas of Washington, Oregon, northern Idaho, and Montana. It consists of approximately 7,600 miles of transmission lines and 190 substations. In the past 4 years, the number of stations operated by supervisory control has increased from 4 to 23. The majority of the supervisory control equipment in service is operating over power line carrier channels of various types. A few installations operate over leased line and cable, and some equipment has been installed and tested for operation over microwave.
