Photovoltaic system debugging of three main consideration is what?

After completed pv system installation and acceptance, and formally put into use before they can debug this step, and it is essential to need attention to one job. Only by experts, after debugging good to officially put into operation,

photovoltaic system after the acceptance of the installation, before officially put into use, need to debug, which is an indispensable work, need attention. Only debugging, with experts to be put into operation. Specifically, the photovoltaic system debugging need to pay attention to the following three main problems. One, pay attention to the debugging operation shall comply with the provisions of the state and requirements of photovoltaic system debugging by has the corresponding qualification units and departments in accordance with regulations of the state, industry and local power grid enterprise test project and qualification standards, test content in accordance with the specific provisions issued by the state. During the project, if the state has issued a new standards and regulations and the administrative departments of electric power, should be adjusted according to the information, in order to meet the requirements. Second, pay attention to the correct order of photovoltaic system debugging. Normal order is debugging photovoltaic string first, through test again after debugging other aspects in turn. Photovoltaic power generation system connected to the electricity grid test point is photovoltaic power generation system integration points. With appropriate qualification tests shall be made by the specialized agencies or departments, test before the test plan should be submitted to the owner and the grid enterprises for the record. Three, pay attention to run after a period of time, to provide the test report the bidder is responsible for the light in the photovoltaic power generation systems interconnection to owner and power grid companies within 6 months after the working characteristic of the photovoltaic system test report, the tests shall be carried out under the good irradiation environment. For example, should be tested, including voltage imbalance, the power quality. And parallel operation flexibility, security protection function, etc. In addition, it is necessary to pass the test to prove that the parallel operation parameters meet the design requirements of network equipment, photovoltaic power generation system satisfies the requirement of grid related, for power system satisfies the requirement of field use. Any nonconformities found in test should be performed by the bidder at his own expense, until qualified.
