State Power Investment corporation: to create intelligent photovoltaic to lead the industry development

In recent years, the State Power Investment Corporation Yellow River Upstream Hydropower Development Co., Ltd. has developed into the largest photovoltaic power station operator in China and even the world in accordance with the requirements of the provincial Party Committee and the provincial government to build the largest photovoltaic power generation base.  In the process of promoting the rapid development of photovoltaic industry, the company not only creates the whole photovoltaic industry chain, implements water and light complementary measures to improve the power generation efficiency of photovoltaic power stations, reduce manufacturing costs, but also under the care and support of the provincial Party Committee and the provincial government and the State Power Investment Group Corporation, constantly develop ideas, innovate and upgrade.  It takes the lead in the industry to build 12 MW smart photovoltaic power plants in Laxiwa and 200 MW smart photovoltaic power plants in Golmud Phase iii, and joins hands with Huawei smart photovoltaic solutions to lead the industry.  

Photovoltaic power stations are mostly built in various remote desert areas, which are characterized by large number of power station components, large area and few personnel.  Yellow River company republican to reach 1550 mw photovoltaic power station, the whole plant a total area of more than 42 square kilometers, 6.5 million groups of various kinds of components, support more than 160000, artificial normal patrol need 24 days at a time, it not only bring great test to the power station daily inspection tour, also formed a lot of pressure to fault handling, and equipment maintenance,  Finding a single point of failure in such a large plant is like looking for a needle in a haystack.  

At present, relying on Huawei intelligent photovoltaic power station solutions to achieve the "centralized monitoring, remote diagnosis, implementation of maintenance" function, so that the actual operation and maintenance of photovoltaic power stations more quickly, efficient, accurate and timely. Through the "centralized monitoring" of intelligent photovoltaic power stations, 31 photovoltaic power stations of Yellow River Company have realized the intelligent operation mode of unmanned and remote centralized control.  Through the "remote diagnosis" brought by intelligent photovoltaic, faults can be precisely located to each group, reducing the difficulty of on-site fault diagnosis, and remote expert assistance, technical resource sharing, improve the timeliness and work efficiency of fault removal.  The "real-time maintenance" function based on intelligent monitoring and remote diagnosis makes the maintenance of the power station less wait, easy to perform, quick to solve, and reduce the loss of power generation caused by faults.  

As a high-precision sensor in photovoltaic power station, the intelligent inverter used by intelligent photovoltaic power station is not only the brain of photovoltaic power station, but also the core and foundation of the whole intelligent photovoltaic power station.  The intelligent inverter adopts advanced chip and software system, which can collect voltage and current of each group respectively. Its detection accuracy reaches five parts per thousand, which is six times that of the traditional scheme.  

Intelligent photovoltaic power station of the Yellow River company also can be realized with the aid of carrying GPS, infrared imaging, and wireless transmission equipment of unmanned aerial vehicle (uav), the component of thermal imaging scans, according to set good accurate flight path, and precise positioning are hot spots, such as hidden crack fault components, combined with image analysis and expert diagnosis, implementation experts and field operations staff to work together,  With real time video and voice communication, let the remote experts to provide "one-stop" professional, safe and accurate technical support, comprehensive, accurate, timely discriminant equipment failure, at the same time by covering the entire photovoltaic power station of special 4 g wireless system, implement quick change of information, the remote fault diagnosis, to improve the reliability of the power station equipment,  Ensure that each string of pv modules is always in optimum working condition.  

Smart PHOTOVOLTAIC power station can also transmit the signal collected by the high-definition camera of the power station through wireless data in real time, and can increase the control point at any time, or adjust the monitoring position, without rearranging the optical fiber.  Inspection personnel can through the video monitoring, thermal power plant and power plant equipment surrounding the to fix, real-time video monitoring and combined multimedia dispatching platform, anytime, anywhere viewing stations in different regions, not only achieved rapid, no dead Angle monitoring, more realized the photovoltaic power station "unmanned on duty, less unattended" innovation mode of operation and management.  

Compared with traditional photovoltaic power stations, intelligent photovoltaic power stations have simple structure and no DC bus box, DC power distribution cabinet and other equipment. The failure of a single equipment does not affect the operation of other equipment, which greatly improves the reliability of the system, reduces the failure rate, and the actual utilization rate of installed capacity is high, and improves the power generation efficiency.  

In the future, the company will further increase investment in scientific research of the Yellow River, high-end talent gathered, vigorously develop crystalline silicon photovoltaic frontier technology research, to develop feng shui light can complementary and coordinated control technology research, to create good two kilowatt clean energy base, to create innovation, intelligent photovoltaic (pv) to lead the global photovoltaic power station construction and development.
