配电自动化系统的实时SOA架构研究

Study on real-time SOA for distribution automation system

研究了SOA架构在配电自动化系统中的应用,针对配电自动化系统的特点与要求,提出了一种实时SOA架构方案。通过对SOA架构的实现技术进行改进,采用多播和P2P技术,满足了SOA应用于配电自动化系统的高实时性要求。通过对SOA上命名相同的服务进行冗余备份的技术,提高了配电自动化系统的可靠性。采用总线适配器实现了实时SOA架构与IEC标准的融合,方便地实现了配电自动化系统的跨平台性,提高了配电自动化系统'即插即用'的灵活性。最后给出了配电自动化系统实时SOA的总体架构,实际应用表明,提出的实时SOA架构方案在保持SOA开放性特点的同时,提高了实时性,完全满足配电自动化系统的应用需求。

This paper studies the application of the SOA architecture in the distribution automation system. According to the characteristic and demands of distribution automation system, a real-time SOA architecture is put forward. By improving the realization technology of the SOA, including the multicast and P2P technology, the new architecture can satisfy the real-time demand of distribution automation system. To improve the reliability of the distribution automation system, the real-time SOA uses the same service named for redundancy backup technique. The new SOA architecture integrates the real-time SOA and IEC standard by bus-adapter to easily realize the cross-platform feature and the flexibility ＂plug and play＂ in distribution automation system. The overall architecture of real-time SOA of distribution automation system is given in the end. The practical application shows that the real-time SOA architecture can meet the real-time demand and still keep the characteristics of openness of SOA.
