Photovoltaic power station project workflow

In the western region in China since 2002, the implementation of the 'power to the countryside' project, which in qinghai province were built more than 100 solar photovoltaic power station, as a result of these power stations were built in remote rural pastoral area, natural conditions, poor traffic conditions, low level of culture,

since 2002, in the western parts of China to implement the 'power to the countryside' project, which has built more than 100 solar photovoltaic power station in qinghai province. Because most of these power stations were built in remote rural and pastoral areas, the bad natural environment, poor traffic conditions and the low level of education has brought power plant operation and maintenance of certain difficulties. From the perspective of the practical experience of solar photovoltaic power station operation management, in order to guarantee the safety of photovoltaic power generation system, economic and efficient operation, it is necessary to establish a standardized and effective management mechanism, in particular to strengthen the operation of the plant maintenance management. Based on qinghai independent photovoltaic power station as an example, this paper introduces the photovoltaic power station operation, maintenance and management experience. 1. To set up perfect technical document management system. Each plant shall establish a full and complete technical data file, and designated persons are responsible for the management of power technical documents, providing powerful technical basis for safe and reliable operation of the plant data. 1. 1 set up the technical filing and design construction drawing power station equipment. This is the basic power plant technology documents, mainly including: the design and construction, completion figure; Acceptance documents; The basic working principle, technical parameters of each equipment, equipment installation and equipment debugging steps; All operating switches, knobs, handles and status, and the description of the indicator; Equipment operation procedure; Power plant maintenance project and content; All maintenance maintenance plan and operation procedure of the project; Power plant troubleshooting guide, including detailed inspection and maintenance procedures. 1. 2 power plant information management system is established. Computer management system for building power plant information data, and establish a database for each plant. The database includes two aspects. It is the basic information of the power station, mainly includes: meteorological and geographical data; Traffic information; Plant location information ( Such as population, households, public facilities, traffic, etc. ) ) ； Power plant related information ( Basic equipment such as power stations, the construction scale, parameters, construction time, current time, design and construction units, etc. ) 。 ) 。 Second, power station's dynamic information, mainly including: 1) The plant power supply information: power users, power supply time, load conditions, total output, etc. 2) Failure in operation of the plant and processing methods: on the problems in the operation of the power station equipment and troubleshooting methods are described in detail and statistics. 1. The establishment of 3 plant operation period file 1. 3. 1 power station daily maintenance record this work is to analyze the running status and maintenance plan of one of the important basis. Routine maintenance is mainly measured at different time every day and record the working parameters of the system. The main measurement record includes: time and record the date; The weather conditions; The environment temperature; Battery at room temperature; Times square matrix of current and voltage; Battery charging current and voltage; Battery discharge current and voltage; Inverter DC input current and voltage; Output current, voltage and power of ac power distribution cabinet; Notes, etc. 1. 3. 2 power plant fault maintenance record when power failure occurs, the plant operation personnel shall record in detail the failure phenomenon, and assist maintenance personnel for maintenance work. After troubleshooting, should fill in the power plant fault maintenance records. Main record includes: failure device name, failure phenomenon, failure time, fault handling methods described, parts replacement records, maintenance personnel and repair time, etc. 1. 3. 3 power station inspection report inspection shall be made by professional and technical personnel on a regular basis. Inspection process, should fully check all plant equipment running state and running state, and measure the relevant parameters. Carefully check the plant operation personnel daily and monthly maintenance records, analysis data, timely guidance for power plant operators to make the necessary maintenance work. At the same time, integrate the problems found during the inspection of power plant in the maintenance operation condition analysis and evaluation, finally make a detailed summary report to the inspection of the plant. 1. 4 set up operation analysis system, the operation of the power station during the period of archives, organize relevant departments and technical personnel to analyze the power station running status, discover the existing problems, and puts forward the feasible solution. Through the analysis of the running system, which is beneficial to improve the ability of technical personnel's business and the reliable operation of the plant level. 2. Perfect the content of the project of maintenance management, and constantly sum up the experiences of maintenance and management and detailed inspection and maintenance of the content of the project, to ensure that does not leak during the process of inspection and maintenance, maintenance level enhances unceasingly.
