Recommended engineering practice to enhance the EMI/EMP immunity of electric power systems

摘要

Many papers and reports have been written on studies conducted by the Oak Ridge National Laboratory and investigations by others on the effect of high-altitude electromagnetic pulses (HEMP) on electric power systems. More than 100 of the published unclassified documents were reviewed with the objectives of: 1. summarizing the mitigation methods suggested in the documents and providing a subjective evaluation of each 2. discussing various standards . that presently apply to the effects of HEMP on utility systems and suggesting additions or modifications or new standards where deficiencies appear to exist; and 3. recommending future studies or actions to improve the utility response to HEMP. While all three components of HEMP were mentioned, only the early-time short-duration E(sub 1) pulse and the late-time long-duration E(sub 3) pulse were considered in detail; the E(sub 2) intermediate component was not considered to affect the power system significantly.
