中文摘要:针对传统的主备切换方法只能支持双机,仅支持心跳一种判断标准,需要人工介入进行切换,且存在单点故障等问题,本文提出了一种基于细粒度应用管理的多机主备冗余机制。该机制通过使用细粒度应用管理、多种条件的故障检测、分布式状态转换等技术,实现了多机主备冗余和资源充分利用,并且切换过程无冲突,无需人工干预。最后通过多场景下的多次测试,验证了本文机制在功能、性能方面的良好表现。本文的多机冗余机制已在国调、华北、江苏等多个调控机构得到了应用。

Design and implementation of the fine-grained multi-machine redundancy mechanism for Power Grid Dispatching and Control Systems
Abstract:In view of the traditional active/standby switching methods can only support two machines, only support heartbeat for judging standard, manual intervention is required to perform the switch, have problems such as single point of failure and so on. In this paper, a fine-grained multi-machine redundancy mechanism for power grid dispatching and control system is proposed. Through the use of fine grained application management technology, fault detection in a variety of conditions, distributed state transformation, this mechanism realizes the redundancy and resource utilization of multi-machine cluster. And there is no conflict, no manual intervention during switch process. Finally, several experiments in different scenarios were conducted to verify the function and performance of the mechanism in this paper. The redundancy mechanism of this paper is adopted in the power grid dispatching and control system such as State Grid, North China, Jiangsu and so on.
