On February 9, 2022, Hitachi Power Solutions held an online press conference, using drones and AI (artificial intelligence) to inspect the blades of wind power generation wind turbines, formulate maintenance plans, and identify damaged and deteriorated areas. We announced a one-stop blade total service that also includes repairs. It is characterized by being able to reduce equipment stoppage time due to inspection to 1/3 compared to conventional systems. As one of Hitachi, Ltd.'s (hereafter, Hitachi) digital solution group "Lumada", it will be provided to wind power generation operators from April 1 of the same year. The blade inspection system using drones was jointly developed with SENSYN ROBOTICS, which has extensive experience in using industrial drones. The drone flight route is automatically set for each wind power generation facility, and high-definition image data is captured from five directions for a single blade. This image data is sorted and managed by site, shooting direction, etc., and the state of damage is evaluated by image analysis using AI. Conventionally, inspections of a single wind turbine with three blades were taken by workers from the ground using the zoom function of a digital camera over a period of two to three hours. This can be shortened to about an hour by using a drone. In addition to inspections, by providing a one-stop service that includes maintenance planning and repair of damaged or deteriorated areas, it is possible to reduce the frequency of repairs that require facility shutdowns of one to two weeks. "For wind turbines, which are said to have a lifespan of about 20 years, it is important to reduce downtime during that time. Blade total system, which centrally manages data from blade inspections to maintenance plans and repairs. We can achieve this through our services,” says Hitachi Power Solutions.
The size of the domestic market for inspection and repair of blades is approximately 3.5 billion yen
Currently, there are said to be about 2,500 wind turbines in Japan, and nacelle falls and blade damage are increasing. ing. In particular, the blades are the most frequent location for accidents and failures due to inadequate inspection and poor maintenance. In addition, the Ministry of Economy, Trade and Industry has revised the technical standards for wind power generation equipment, and inspection and repair of blades are becoming more important than ever. To date, the Hitachi Group has received orders for 860 wind power generation facilities, and for 461 of these in Japan, Hitachi Power Solutions has been in charge of commercialization planning, design, construction, operation management, and maintenance services. have a track record As for repair services, we have developed 9 service centers, 2 factories, and 1 parts center in Japan, and have provided a total of more than 600 units. Until now, Hitachi Power Solutions has provided maintenance and repair services mainly for wind power generation equipment manufactured by Enercon of Germany, an alliance partner of the Hitachi Group. In the future, assuming that the domestic market for inspection and repair of wind turbine blades is about 3.5 billion yen, we will actively expand the business outside the Hitachi Group by combining it with a blade inspection system using drones jointly developed with SENSYN ROBOTICS. We are planning to expand.
