IEC 61850 Compliant N-1 Inter Trip Scheme Suitable for Japanese Connect and Manage

Abstract

To expand the introduction of renewable energy, it is necessary to efficiently utilize existing power systems without relying on system enhancement. One of the efforts is N-1 inter trip. N-1 inter trip is a mechanism to expand the operating capacity in normal times by controlling power generation in the event of a single failure in power transmission and conversion equipment. However, since it is difficult to realize an N-1 inter trip scheme with existing equipment, new development is required. Therefore, in this paper, we report an N-1 inter trip scheme that implements an IEC 61850 compliant MMS communication system and is highly functional and can be realized at low cost.
