Study On The Lean Maintenance Mode For The Basin Cascade Hydropower Stations Group

Hydropower overhauling is specialized in services of the hydropower equipmentmaintenance,with the high technologies and professional requirements, poor workingconditions, repair resource constrained, strong time constraints，directly impacting onthe hydropower station operation reliability, security, and economic benefits. With theSociety and economic development of our country, the demand for clean energy isgrowing, Hydraulic can provide a lot of high-quality green energy. China ’s waterresources are very rich, most of the rivers are developed by the approach to basin,cascade, scrolling, comprehension, having formed the thirteen hydropower basesmade up of the Dadu River, the upper reaches of the Yangtze River, the upper reachesof the Yellow River, Wujiang River, the Jinsha River, Nu River, Red River ofNanpanjiang,rivers in the three northeastern provinces, the Xiangxi Rivers, YarlungRiver, the Lancang River, the Yellow River mainstream and Fujian, Zhejiang andJiangxi Rivers, etc. Facing basin cascade hydropower stations group equipmentmaintenance, due to more cascade hydropower stations, the maintenance time domainbasically in the same time as well as limited maintenance resources, exploring anddeveloping a basin-oriented maintenance mode of the cascade hydropower stationsgroup is the urgent problem of Hydropower overhauling.The paper,on the basis of analyzing and studying the development of hydropoweroverhauling and the status quo of research at home and abroad as well as relatedtheories, absorbing the outstanding achievements, Combining with the characteristicsof the basin cascade hydropower stations group, Puts forward to the Basin cascadehydropower stations group maintenance mode, the main contents include: the basinmaintenance control center or the maintenance company, the centralized managementmode of the watershed maintenance, the flat basin overhaul matrix organizational model,the mode of operation based on multi-project watershed maintenance.The Basin-oriented maintenance company, is mainly responsible for the maintenance of the basincascade hydropower stations, the hydropower scientific management and control;Centralized management model for the watershed-oriented overhauling to the basincascade hydropower stations group is to implement a centralized and unified,comprehensive system management;The basin-oriented overhauling flattened matrixorganizational model is to build an efficient and streamlined service-oriented organization, breaks all kinds of obstacles, inspires the organization’s overallcreativity, enthusiasm, fully utilizes and mobilizes resources for the watershedmaintenance services, improves the maintenance operational efficiency;The mode ofoperation of the multi-projects based on the watershed maintenance is to conduct acomprehensive analysis and evaluation on the the basin maintenance needs informationand works out the overall maintenance of the watershed planning,then, embodies theoverhauling planning in a number of maintenance projects, by the way of themulti-project management, carries out the business of the overhaul of the entire basin,achieves the lean maintenance of the basin cascade hydropower stations groupFinally, the results of research are applied to the maintenance of the Dadu Rivercascade hydropower stations group. through specific maintenance case, the centralizedmanagement model, the flattened matrix organization mode and the mode of operationbased on the multi-project management are applied in the case, and implement andprospects are analyzed, achieving satisfactory results, also providing the reference forthe maintenance management of other basin hydropower.
