摘要
在输配电网系统的运行中,为及时便捷的追溯配电网的运行状态,必须对设备的工作电流、电压、开关动作和设备故障指示器等状态参数信息进行实时存储与挖掘分析。随着配电网智能化、信息化水平的提升和新一代能源自动化系统的接入,配电网运行的数据规模倍增。传统关系型的数据库在海量关系型数据的采集存储、分析处理、数据安全等方面存在不足,采用负载均衡数据库技术能够优化配电网的管理和分配,消除电网的内部负载不平衡,提高系统异常反应的速率和系统总体的性能,同时提升系统运行可靠性。利用负载均衡数据技术,可根据业务量灵活分配电网资源,使得系统管理和扩展的能力也得到了提高,实现配电网运行数据精益化管理目标。
In the operation of the distribution network system,in order to facilitate the tracing of the status of power grid equipment,it is often necessary to store and analyze the relevant data of the equipment’s current,voltage,switching action,and fault indicator.With the improvement of the intelligent and informatization level of the distri⁃bution network and the access of a new generation of energy automation system,the data scale of the distribution network operation has doubled.Traditional relational databases have insufficient storage and processing capabilities for massive data,and data security cannot be met.The load balancing technology optimizes the distribution of the distribution network,eliminates the load imbalance of the power grid,and improves the response speed and overall performance of the system.Load balancing can monitor the operating status of the power grid,detect abnormal oper⁃ations in a timely manner,and transfer access requests to other outlets that can work normally,thereby improving the reliability of the entire power distribution system.After the load balancing technology is adopted,the power grid can be flexibly allocated according to the development of business volume,the system’s scalability is improved,and management is simplified.
