Quality of the construction of the photovoltaic power station should be how to shut?

How to improve the quality of photovoltaic power station construction, control of power plant equipment performance parameter and ensure the smooth grid-connected power generation plant and through the acceptance? This needs with the help of a professional instrument to test the power station equipment, control over the quality of power plant construction, as well as the construction of the

how to improve the quality of the construction of the photovoltaic power station, the control performance parameters of the power station equipment, ensure the smooth progress of power grid generation and through the acceptance? The need to use special instrument to test the power station equipment, power station construction quality examination, and construction technology of construction personnel training. 1, quality supervision, inspection and performance test methods according to the needs of photovoltaic power station construction stage, the need to develop scientific and rational stage to supervise and inspect the work plan, including: equipment on-site inspection and acceptance, installation and debugging phase of quality supervision, inspection, commissioning stage of equipment performance test, ate test for intelligent detection software, etc. Ensure that each stage of the construction without problems and hidden dangers. 2. Construction instance power quality problem, for example, power station, after construction acceptance often assembly level can not meet the requirement of the specification, support for design and installation Angle error: due to the wiring method is not reasonable, erector dragging cable on the surface of the sand, prompted a common terminal box of wire bunch of scratches: junction box grounding line did not pick up, at the bottom of the transformer in cable trench is not blocked, transformer accident put oil and put the tubing, to put the tank without inverter voltage meter is damaged, bubble in transformer oil temperature controller not out: some power station there are quality problems, such as mother box inverter and change without box number, inverter without fire equipment surrounding box transformer, switch room lightning arrester insulation damage, etc. If timely found these problems in the construction process, compared with the power station is completed, will greatly reduce the workload. At the same time, the equipment performance tests after the plant was put into operation, often found in the slot insulation skin damage, low insulation resistance. In addition, due to the grounding line connection irregular or bolts rust, grounding resistance is greater than the specification requirements. Some parts covered by dust or damage, lead to appear on the parts. Junction box electrical connection in the loose cause fever: in addition, the inverter of the conversion efficiency is low, poor quality of the output power, the system efficiency is lower than the design value, debris, crack, broken gate, black side, such problems as low efficiency, process pollution. Detected by the electroluminescent element is significant. Even some power plant unit in operation, the attenuation is higher than the procurement technical requirements. Above the quality problem of the photovoltaic power station need reliable and effective quality control measures to conduct a comprehensive inspection, in order to find problems in a timely and effective manner, according to different situation provide targeted solutions to ensure reliable power station during the 25 years life cycle run efficiently. 3. Test method for the traditional photovoltaic power station to test can only rely on people walking around the station of random sampling. Sampling is usually random and unrepresentative test can find problems is limited. As the 'Internet +' application in the industry and the promotion, photovoltaic power station equipment intelligent online monitoring and fault diagnosis analysis technology becoming mature, can carry out 'offline professional testing' and 'online intelligent monitoring and diagnosis' of combining the O2O testing services. By conducting a complete coverage of photovoltaic power station construction intelligent on-line fault monitoring, implementation of photovoltaic power station in real time and accurate fault location, fault diagnosis and timely found pv set of string for zero current, low current, low photovoltaic inverter output power, all kinds of problems such as communication failure. According to the power failure diagnosis and elimination report, the owner can eliminate defects in time before the project acceptance, reduce hidden trouble, eventually improve the level of quality and performance of photovoltaic power station equipment, so as to improve the capacity of photovoltaic power station put into production after.
