Design and Realization of Substation-Control Center Two Level Distributed Alarming System

Abstract:

This paper proposes the construction mode of a two-level distributed alarming system, in which alarms are coordinately processed by substations and control center. In substation side, we classify alarms into several grades according to the degree of their importance and send the extracted key alarms to control center, thus reduce the amount of alarm passing and ensure the transmission reliability and speed; meanwhile, we carry out alarm verification and pretreatment through information redundancy to validate alarm correctness. In control center side, we integrate the data of ordinary Supervisory Control and Data Acquisition (SCADA) and the alarms received directly from substations, and carry out comprehensive fault reasoning and correctness verification. In order to illustrate the feasibility of the substation-control center distributed alarming system, the overall structure, substation smart alarm (SSA), control center smart alarm (CCSA) and cooked data transmission of this construction mode will be discussed in detail.
