基于消息中间件的用电信息采集系统远程停复电可靠性方案*

通过用电信息采集系统实现快速、精准的远程停复电对于提升电网企业精益化管理水平、提高客户服务满意度至关重要。文中详细分析了现有用电信息采集系统远程停复电业务处理流程,揭示了系统在高负载、多业务协同处理时出现的处理延迟、调度缓慢、主站与电能表停复电服务程序操作及数据不一致等影响停复电业务执行成功率的不利因素；针对上述不可靠因素,提出了一种基于消息中间件技术的远程停复电事务处理架构,该架构的对现有用采系统改动较少；并且基于该架构,文中设计了一种满足远程停复电可靠性需求的分布式事务处理方案；通过仿真分析可知,该方案可以有效提高用电信息采集系统执行远程停复电业务的可靠性。

Reliability-guaranteed scheme of remote power cutoff and recovery for electricity information acquisition system based on message middleware

Rapid, accurate remote power cutoff and recovery through the electricity information acquisition system is important to improving the economic level of power grid enterprises management and improve customer service satisfaction. This paper analyzes in detail existed process of the remote power cutoff and recovery by the electricity information acquisition system, and reveals the disadvantages of the process affecting the success of the remote power cutoff and recovery, such as high load processing delay, slow task scheduling for multi-business cooperation, operation and data inconsistent of power cutoff and recovery service program between the master station and the electricity meter. In order to address the above unreliability factors, a remote power cutoff and recovery transaction processing architecture based on message middleware technology is proposed, which can reduce the complexity of system rebuild. Based on this architecture, a distributed transaction processing scheme is designed to meet the reliability requirements of the remote power cutoff and recovery. The simulation results show that the scheme can effectively improve the reliability of the remote power cutoff and recovery through the power information acquisition system.
