Hardware System Design of Condition Monitoring and Fault Diagnosis System for Hydrogenerator Unit

The system of the fault diagnosis system hardware was designed.

1:B Article ID: 1006 1 Author 1 Introduction: Wu (1 evasion -) male (Professor Wenshan A from Yunnan) is mainly engaged in the teaching and research work of the magic system computer system Ved.http:// The generator set condition monitoring and fault diagnosis system is a computer-managed online monitoring analysis and diagnosis system consisting of sensor components, pre-data acquisition and processing systems, computers, signal monitoring and analysis software, status reporting software, database and diagnostics. It can monitor the vibration, displacement, temperature, pressure and stator air gap of each part of the unit in real time, provide the unit's mechanical status information, real-time alarm, perform early fault diagnosis, and provide comprehensive status report.

The hardware system mainly refers to the three subsystems of the sensor, the pre-data acquisition system and the host computer system, and gives the form of the whole system.

*In the school's foundation, the sub-worker A's signal nickname is 1 Department a Liu Dawei. Turbine Beijing: China Water Conservancy and Hydropower Press, 1996. Wuhan: Huazhong Institute of Technology, North China Institute of Water Resources and Hydropower, etc. Installation and maintenance of hydraulic units. The power industry came out of Wuhan Water Conservancy and Electric Power College, and so on. Hydraulic unit auxiliary equipment and automation. Power Industry Press, 1979. Chen Runtai, Xu Wei. Detection technology and smart meters. Central South University of Technology Press, (Continued from page 55) 3.2 High-speed and metered water wheel generator set condition monitoring and fault diagnosis system using multiple AD boards in parallel, on the one hand added the number of channels, more importantly By means of parallel acquisition, the sampling frequency of a single channel is added. In other words, the number of AD boards can be increased, which can significantly increase the sampling frequency. This is achieved by hardware modularization of the status monitoring and fault diagnosis system of the hydro-generator set. The number of different sampling channels and sampling frequency provide the most convenient and flexible way.

3.3 Data Processing of Data Acquisition System of Smart Key Phase Lower Computer One of the most important problems is the processing of key phase signals, that is, how to achieve synchronous sampling.

At present, due to the development of computers, memory capacity and CPU speed are greatly improved. Therefore, it has become possible to collect a large amount of data and calculate values. The method used in this system is that, corresponding to each unit, an IPC is responsible for collecting at the maximum speed that the system can achieve (obviously, its density is much greater than the density of the data we require). The incoming data is processed by another IPC to get the required data. The key phase signal is inserted into the collected data in the form of an interrupt signal. As a basis for data processing, the appropriate phase interpolation value is corrected by an appropriate interpolation algorithm, thereby ensuring synchronization of data acquisition. High speed and continuity.

3.4 Network Communication The network used in this system is Ethernet and adopts TCP/IP protocol. For local networks, various protocols can be used. TCP/IP is not the most efficient. However, due to the expansion of the network in the future, it is necessary to use the TCP/IP protocol because it is supported by each LAN. It is also convenient to use the Internet for long distance communication.

3.5 Screen display Originally, for the lower computer, as the software data collector, as long as it can perform data acquisition and processing functions, but for the convenience of debugging and joint adjustment, at the same time, in order to achieve a certain man-machine dialogue, to change a certain Some parameters, the software part of the lower computer plus the screen display part, the collected data is displayed on the screen in a certain way.

The screen display part is divided into two aspects. On the one hand, the data is displayed in a graphical form, that is, it is used as an oscilloscope to monitor the data collected, and on the other hand, a dialog box for setting parameters is displayed to implement parameter setting.

4 Conclusion In the hydroelectric generating unit condition monitoring and fault diagnosis system, the hardware system is the basis for realizing various functions. The pertinence, reliability and openness of the hardware system have an important impact on the application of the entire system and further functional expansion, so it has been given considerable attention.
