SCADA-Based Monitoring and Remote Control of Circuit Breakers

摘要

This paper presents a descriptive analysis of automated supervisory control and Data Acquisition (SCADA)-based monitoring and remote control of circuit breakers. The automated supervisory control and Data Acquisition (SCADA) system architecture has two main parts – The Hardware and The Software. The hardware comprises the circuit breaker monitor (CBM), the personal computer (PC) concentrator and the Global Positioning System (GPS) clock receiver. The circuit breaker is made up of the intelligent electronic devices (IEDs) which are found in the breaker cabinet in the switchyard. The global positioning system (GPS) receiver and the personal computer (PC) concentrator are also found in the control house. A point to multipoint (wireless) connects the personal computer concentrator with the intelligent electronic device. This kind of arrangement work as master-slave architecture. The circuit breaker monitoring slave unit is positioned at each breaker in the switchyard and are wired together to achieve the signals from controlled circuit breaker.
