摘要
采用SSH(SecureShell)和WebSphere提出并实现了一种通用的适合于电力市场的安全高速通信通道的方案。文中所有电力市场的信息均采用基于可扩展置标语言(XML)的简单对象存取协议(SOAP)语言进行描述,保证了通信系统与电力市场其他子系统对接的柔软性和扩充性。整个通信系统采用基于Java的Java2平台企业版(J2EE)和Java消息服务(JMS)技术实现。所采用的中间件产品(包括SSH,WebSphere)、信息描述方式(包括XML,SOAP)和实现技术(包括J2EE,JMS)适用于任何操作系统。实验结果表明,该通信系统可实现电力市场实时数据最大4次/s的刷新,厂站端与交易中心之间的一次实时交易往复过程最大不超过2s,完全能够满足电力市场实时数据通信的要求。
A secure and high-speed communication channel especially for electricity market using SSH (secure shell) and WebSphere servers has been proposed and realized. This communication channel can be used not only in the public Internet environment through ISDN/PSTN/ADSL, but also in the dedicated Power Data Network. All of the information involved in electricity market is described in SOAP (simple object access protocol) based on XML (extend makeup language), which guarantees the flexibility and extensiveness of this channel when integrated with other sub-systems of the electricity market. This communication channel is realized by adopting J2EE (Java2 enterprise edition) and JMS (Java message service) technology. All of the middle-wares used (SSH, WebSphere), the information description (XML, SOAP) and the realization technology (J2EE, JMS) are suitable to any operating system. Test results show that, with this communication channel, the real-time data of electricity market can be updated up to 4 times per second, one on-line trading between the market and the counterparty can be done within 2 seconds at most.
