【摘要】 现有继电保护整定计算软件大多需要开发、部署和操作不同的定制代码来支持不同的用户。在这些系统中,需要为每个用户部署和操作单独的实例代码。这导致了高的开发和维护成本,限制了其在中小电力企业的应用。随着SaaS的出现,提出了一种SaaS模式下继电保护整定软件框架,描述了SaaS模式的系统核心模块、服务的开发和托管,并设计了图形界面。SaaS模式应用的自定制和对于持续增长的用户数量具有的可扩展性,减少了应用服务提供者的托管成本,降低了用户的使用费用,并能尽快的使用最先进的IT技术。更多还原

【Abstract】 Most relay protection setting calculation software today, different customized code has to be developed, deployed and operated to support each user. A separate instance of the code has to be deployed and operated for each user in these systems. This lead to high development and maintenance cost, limited its application in small and medium-sized electric power enterprise. With the emerge of Software as a Service(SaaS), We present a kind architecture of a relay protection setting software under SaaS mode, and described the method used in the system core module under SaaS mode, development and hosting of services, and designed the graphic interface. The new SaaS model reduced the application’s hosting cost and user’s use fee because of its capabilities in customization and scalability while continuing to support the increasing number of users. It further benefits users by immediate access to the lastest IT technology.更多还原
