| 摘要: |
| 分析了GEN3-EMS以及该系统数据服务接口(DSI)的特点,并以从SCADA/EMS实时库中读取线路潮流值为例,探讨了DSI的应用原理和调用步骤,包括资源初始化、请求执行和资源释放过程。基于GEN3-EMS平台开发了电网断面潮流在线监测系统,实现了断面运行方式规则库定义、线路运行状况和断面运行状况在线监测等功能。结合DSI调用特点对断面潮流监测流程进行了优化:将DSI的初始化过程和释放过程并入系统的启动和关闭过程中,而在系统监测定时器单元只执行DSI请求执行过程;采用参数值相等规则在DSI调用中只读取需要监测断面的线路遥测数据以减轻系统负荷;设置自动初始化和人工初始化功能以满足不同的需要。流程优化后,监测定时器设为2s,CPU资源占用率仅为0.3%,提高了系统运行的稳定性和可靠性。 |

| Abstract: |
| The characteristics of GEN3-EMS and its DSI(Database Service Interface)are analyzed.The DSI application principle and DSI calling process,including resource initialization,request execution and resource release,are discussed with an example of reading power flow monitoring data from real-time SCADA /EMS database.An on-line sectional flow monitoring system of electric power grid is developed on GEN3-EMS platform,which realizes the definition of electric section operating rule base and the on-line operating state monitoring of lines and sections.According to the characteristics of DSI call,the power flow monitoring process is optimized:only the DSI request execution is implemented in the monitoring timer unit while the DSI initialization and release are integrated into system initialization and close respectively;only the line telemetering data needed are read in DSI call to reduce CPU load by applying the equal attribute rule;automatic and manual initializations are set to meet different requirements.After optimization,the CPU utilization is only 0.3 % when the monitoring timer is set to 2 s,with the system stability and reliability greatly improved. |
