Circuit Breaker Maintenance by Mobile Agent Software Technology
Circuit breakers are crucial components for power system operation. The currently adapted time-directed maintenance strategy and the emerging new condition-based strategy require a flexible information processing technique and software architecture. In this paper, mobile agent software has been applied in implementing circuit breaker maintenance and repair tasks. Several potential application scenarios have been described and the relevant software features have been discussed. The benefits of using the mobile agent techniques are discussed at the end.
Circuit breakers are crucial components for power system operations. They play an important role in switching for the routine network operation and protection of other devices in power systems. To ensure circuit breakers are in healthy condition, periodical inspection and preventive maintenance are typically performed. The maintenance schedules and routines usually follow the recommendation of circuit breaker vendors, although the recommended schedules may be conservative.
New maintenance techniques and methodologies are emerging, while the circuit breakers keep improving in their designs and functions . As an example, some new circuit breakers have embedded monitoring instruments available to measure the coil current profiles and the operation timing . The recorded information can be used to monitor the condition of breakers during each operation. In this case, it may be more appropriate to replace the time-directed maintenance by condition-directed maintenance practice
