DESIGN OF TELEMETERING CONFIGURATION FOR ENERGY MANAGEMENT-SYSTEMS

In modern power system control centers, operation and control of power systems are carried out with the help of real-time computers. Live da ta is captured by Remote Terminal units (RTUs) located at various stat ions and transmitted over suitable communication media to the control center for display, monitoring and control. Telemetering equipment for ms a sizable component of the project cost. A methodology is presented in which RTUs are located at different stations to meet certain crite ria such as observability of the system and absence of critical measur ements. Additional reliability constraint of loss of information from a single RTU for the above two constraints is also imposed.
