SUPERVISORY CONTROL OF POWER SYSTEMS: RELIABILITY IMPROVEMENT

摘要

Prediction of future Supervisory Control and Data Acquisition (SCA0A) system configuration is difficult because it is closely related with varyings of strategies of system's control/operation and computer architecture. This paper proposes a new approach to realize a reliable and flexible SCADA system under which application programs can hardly be affected by the varyings. SCOPE is a new infrastructure supporting to build the SCADA system. It consists of "Execution dependence part" and "Operation dependence part" in order to realize a reliable and flexible SCADA system under distributed environments. This paper introduces a new design concept, a reliable technique and the evaluation result on SCOPE prototype system.
