Long term simulation of the Israel power system dynamic response a case study
Long term simulation of the dynamic response of power systems has received much attention for several years. However, there are still numerous difficulties involved in reconstructing widespread disturbances. The authors describe the experience gained at the Israel Electric Corporation (IEC) using long term simulation for the reconstruction of a system wide contingency for a period of 15 minutes. >
This paper designed and implemented a database service multi-point disaster tolerance system.The system monitored the data changes of the primary database in real-time.And the data changes,which were monitored,were replayed on the several remote standby databases in real-time,ensured the data consistency of the standby databases and the primary database.The system detected the failure of the primary database.When the primary database failed,the database service would be automatically migrated to a standby database in few seconds,ensured the service continuity,and improved the disaster tole-rance capacity of the database service.
