| 摘要: |
| 随着电力系统的发展，要求有更加有效的电力系统规划软件支持，三层结构是近年来得到广泛应用的一种C／S应用结构，它将客户端的一些应用功能提取出来加以单独实现，使之成为独立的应用层或中间层，中间层可以提高系统性能，简化系统维护，提供更完善的安全机制，与传统两层结构相比，在数据量大，逻辑关系复杂的情况下，三层结构更加合适。以数据为中心进行集中处理的规划软件需要处理大量的数据和复杂的逻辑关系，有必要采用三层结构实现，探讨了三层结构在电力系统系统规划软件中的应用，并给出了一个实现的实例。 |

| Abstract: |
| Along with the development of power system, more efficient power system planning software is required. Three-tier client/server architecture gets wide use in recent years. It extracts some application functions from client end and realizes solely, making it an independent application tier. The application tier can enhance the system performance, simplify system maintenance, and supply perfect safety mechanism. Compared with the conventional two-tier client/server architecture, it is more practical in the environment of abundant data and complicated logic relations. The power system planning software deals centrally with a great deal of data and it has complicated logic relations, therefore it should adopt three-tier client/server architecture. Its application in power system planning software is discussed and an example is given. |
