| 摘要: |
| 对于提高水电厂自动化系统与多台保护等智能装置之间通信的可靠性和快速性,平衡传输是最佳的选择。对以太网103规约及其在水电厂自动化系统的通信进行了介绍。在以太网的链路中,该规约采用UDP报文与TCP报文相结合。利用UDP短报文进行链路监测和链路启动,链路正常建立后,利用TCP报文进行正常信息传输。当保护智能装置等发生事件或有数据变化时,其自动启动一次TCP报文传输过程,及时将信息通知水电厂自动化系统,成功地实现了正常连接状态下的平衡传输,保证了信息传输的及时性、完整性与正确性。 |

| Abstract: |
| The banlanced transmission is selected to improve the reliability and speediness of the communication between automation system and intelligent protective equipments in hydraulic power plant.Ethernet 103 protocol and its application in hydraulic power plant SCADA system are introduced.103 protocol adopts TCP combined with UDP.UDP data grams are used to initialize the transmission process and check the link state,while TCP to transmit information in normal connection states.When data changes or event occurs,intelligent protective equipments initiate a transmission procedure automatically to send the information to SCADA system in time,which realizes the balanced transmission under normal link states and ensures the reliability,speediness and integrality of information transmision. |
