Research On Key Technologies For Integration Of Province Grid's Maintenance Optimization Management System

This topic intrudoce the construction ideas of the integration of province grid's maintenance optimization management system. The main objects of this system is assessment, optimization, multi-dimensional security check contains static state analysis, transient stat and dynamic state analysis. This system always build a optimize decision support system by grid operating experience, evaluation indicators, static state analysis, dynamic state analysis and transient state analysis, and then, find a propoer solution. First, based on the AC2enterprise service bus, to avoid the directly connection among the applications, reduce the costs of system upgrade and building new features. Secondly, building an integrated network modle management platform to achive the following gloals, such as maintenance the network model at any node and sharing it globally, support the future network model service. Third, support the safety analysis of multi-cycle and multi-dimensional, can do static stablility analysis, dynamic stability analysis and transient stability analysis to the maintenance plan via annual, monthly or daily method. Fourthly, fist proposed and implementd2optimization evaluation index such as equivalent loss of generating capacity and load supply abundant capacity. By quantity analysis these two indicators to tell grid's safety supply capacity, find the security plan which meet the minimun loss of generating capacity and load supply's max capacity, help the user to adjust the security plan. When the system comput the optimization goal, it use flow analysi, sensitivity and security analysis,static security analysis, quantitative assessment the impact of maintenance on the transmission equipemts overload and limit. Finally, study the maintenace schedule optimization, analysis the adequacy assessment informatin, combined with eperts intelligent decision library, give the optimal adjustment to the maintenance play does not meet the safety requirments, assisted the optimizer to arrange the maintenace plan.
