Microcomputer Based Feeder Protection and Monitoring System - Utility Experience

This paper describes the experience of Houston Lighting & Power Company with the field operation of the Feeder Protection and Monitoring System developed by Texas A&M University. The Feeder Protection and Monitoring System (FPMS) is fully described from a functional perspective. The paper describes the design objectives of the project. The field testing of the device and its subsequent use as a monitoring and diagnostic tool are reviewed in detail. The potential value of the system to utilities and the need for modifications and further research are included. The perspective of HL&P on integrated substation control and protection is given.
