2002, China in the western region "SDDX project in Qinghai Province, the construction of more than 100 solar photovoltaic power plants, because these plants were mostly built in the remote rural and pastoral areas, harsh natural environment, poor traffic conditions, personnel low levels of literacy, power plant operation and maintenance has brought some difficulties. From solar photovoltaic power plant operation and management of actual work experience, to ensure that the photovoltaic power generation system security, economic, efficient operation, and must establish a standardized and effective management mechanisms, in particular to strengthen the operation and maintenance of the power station management. Establish a sound technical document management system for each plant should establish a comprehensive and complete technical documents files, and the establishment of the person responsible for the management of the power plant technical documents, provide strong technical basic data to support the safe and reliable operation of the power station. 1. Establishment of power plant equipment technical file and design and construction drawings file basic technical archives of the power station, including: design and construction, as-built drawings; acceptance documents; equipment works, technical parameters, equipment installation procedures, equipment commissioning steps; all operations of the switches, knobs, handles, as well as state and signal indication; equipment running steps; power plant maintenance projects and content; maintenance schedule and all maintenance projects operating procedures; plant troubleshooting guide, including detailed inspection and repair steps and so on. 2. Establish power plant information management system
