Circuit Breaker Maintenance by Mobile Agent Software Technology
Introduction
 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 Breaker Maintenance Tasks

 Mobile Agent Software
Application Scenarios
 Creating Circuit Breaker Failure Reports
• When a circuit breaker failure does happen, some immediate action and follow-up investigation are required
• A mobile agent makes an itinerary according to its knowledge about the location of information sources and will travel to each source and collect the information.
• The agent may also choose to delegate tasks to a bunch of second level agents and edit the last returned result from other agents
• The agent may also utilize some heuristic rules to help determine the possible causes of the failure.
• The generated report is in Extensible Markup Language (XML) format and contains only the necessary information about the failure report

 How circuit breaker monitoring occurs??
Security Consideration
 Mobile Agent Administrator Tool
Logging and Experience Sharing
Cost-benefit analysis
 Agents can assist users in performing some standard analysis.
 For example, to determine whether in-service monitoring of a circuit breaker is satisfied, a cost-benefit analysis based on the risks and investment return may be processed automatically.
 In a decision making sequence has been recommended, which consists of three stages.
 Some historical data will help the user to give a more appropriate score for assessing each failure mode
Summary
 Utilizing mobile agent techniques, the convenience and speed of accessing and generating maintenance data will be improved.
 With increasing complexity of circuit breaker equipment, more information is needed to perform the maintenance work, so an efficient data communication exchange becomes very important.
 Mobile agents can process information locally with less network bandwidth consumption.
 Also its ability to provide reliable transmission on disconnected or low quality networks is an important merit
 Mobile agent computing easily facilitates the integration and automation of the maintenance process, starting from the generation of work orders to the completion of the maintenance report
 Mobile agent computing also provides the means by which real-time and off-line data can easily be integrated into a single distributed maintenance management system.
 Using real-time monitoring data, the maintenance system can evaluate the condition of devices, which makes predictive maintenance possible.
 The integration of real-time data may be utilized to improve the maintenance management decisions.
 The platform independence feature of mobile agents provides interface and support for great variety of devices
Conclusion
 In this paper, mobile agent software has been applied in circuit breaker maintenance.
 Mobile agent software may be suitable for applying in circuit breaker maintenance practice due to its support for heterogeneous systems, security, distributed events, low-bandwidth usage, etc.
 Using the mobile agent software, the development work can be greatly simplified.
 Also, agent-based software architecture makes the application more flexible and upgradable.
