A J2EE and VML Based Optimization and Management System of Generator Maintenance Schedule

To improve the working efficiency and decision making level of power grid dispatching,an optimization and management system of generator set maintenance schedule has been developed by Guangdong Power Dispatch Center.Considering multi-objective and multi-constraint factors,the system adopts improved ant colony algorithm(ACA) and the dynamic figure technology of vector markup language(VML) for optimization,uses J2EE-based three-layer browser-server structure,and applies Java Server Page(JSP) technique to realize the functions such as maintenance schedule optimization of unit,power balance and management of generating progress,providing suggestions for power dispatch center while making maintenance and generation schedule.
