Operational monitoring of the technical condition of hydroelectric plants

The use of a monitoring system, designed to monitor the condition of hydroelectric plants from the vibrational, mechanical and magnetic characteristics under different operating conditions, is considered. The results of a comparative analysis of similar and different types of plants, obtained using the “ALMAZ-7010-GéS” steady monitoring and diagnostics system and new sensors developed by the “DIAMECH 2000” Company, are presented.     

马来西亚巴贡水电站的溢洪道设计

巴贡水电站是马来西亚最大的水电站工程,而岸边开敞式溢洪道作为该工程唯一的永久泄洪建筑物,具有自身的设计特点和难点。在设计中,主要利用1∶50比尺的水工模型试验,对溢洪道的引渠、堰闸段、泄槽的掺气减蚀、挑流鼻坎等的设计进行了研究和改进,解决了溢洪道的水力学、结构和高边坡等问题。尤其是长引渠应当注意渠内流速对泄量和下游流态的影响,以及利用下游地形特点,对比挑距、冲坑和下游防护等,优选了挑流鼻坎的体型设计,对于类似工程的设计有一定的借鉴作用。
