Digital computation of transients and safety testing of mine electrical power systems. Annual report June 24, 1976--June 23, 1977
The report deals with a multifaceted research effort to increase mine electrical system safety. The project can be broken into six task areas. Task one deals with the development of tests and instrumentation to perform these tests that are designed to detect incipient faults on mine power systems. This program also encompasses evaluation of the tests and automation of data collection and recording using a microprocessor. Task two concerns the prediction and suppression of mine electrical transients. This program involves digital simulation and suppression hardware evaluation. Task three deals with the reliability and fail-safe assessment of various components of the mine electrical system including both the protective system and the bulk power system components. Task three also deals with theoretical analysis, laboratory testing, and in situ testing in coal mines of power system devices. Task four is an effort to design an optimal mine electrical distribution system. The initial effort is along the lines of refining analytical tools such as the load flow model. Task five is an attempt to optimize the selection of molded case circuit breakers, makes or models, on the basis of total annual cost. Task six assesses the availability of equipment to satisfy existing Federal regulations.
