1. 5 mw wind turbines gearbox maintenance cost analysis

1. 2019-5 mw wind turbines gearbox maintenance cost analysis 05 - The wind generator with 05 Zhu Hanwu wind power development in our country, stand-alone capacity increasing, 2 new power capacity in China in 2017. 0 mw accounted for 59%, become the mainstream models, more than 2 mw machine accounts for more than 90% and the mainstream of 1 in the last few years. 5 mw type proportion was only about 6. 2%. In service units in 2017, 1. Of the total capacity of 5 mw accounted for 45. Accounts for 8%, than still the biggest, a total of 5. More than 70000 units ( More than 70% for the doubly-fed generator) 。 So 1. 5 mw wind turbines market have already have mature toward a recession, but 1. 5 mw wind turbines running maintenance requirements, in the period of strong indeed there are more than 40000 gearbox for daily operations. Beijing JiPeng information consulting co. , LTD. To the existing one. 5 mw wind turbine maintenance costs for research, analysis of gearbox maintenance cost composition. A gearbox, fault category main failure mainly includes: failure of gear, shaft and bearing, oil leakage fault, pipeline, auxiliary electrical fault, etc. Second, the cost constitute the main gearbox maintenance costs include: spare parts purchase expenses ( Including transportation, mixing, etc. ) , installation, service cost, power loss cost, labor cost and other security, the cost of land expropriation, etc. Three, the main spare parts purchase expense transmission price: 100 - 1. 3 million yuan gearbox scrappage price: 950000 yuan ( Quality assurance 3 - 5 years) Wheel speed ratio change price: RMB 90000 ( Including installation service charge) High speed shaft replacement price: 4. About 50000 yuan ( Including installation service charge) Internal gear transmission price: 2 - 150000 ( Different components) Four, gearbox transmission replacement installation service charge a single single units replacement, installation services in costs about 200000 yuan ( Affected by region, the space and time, the price fluctuations) 。 Five, the ops overall cost according to the survey sample data modeling analysis, 1. 5 mw doubly-fed unit gearbox in operation in the past ten years, Half life cycle) , average each operational cost is about 580000 yuan, among them, the spare parts purchase cost is about 200000 yuan, installation service charge 100000 yuan, power loss cost is about 230000 yuan, Electricity prices in accordance with the 0. 55 yuan/KWH estimate) 。 Note: the above data for the research samples, does not represent a specific platform, a type of fan data, also do not represent the national average data, only supplies the reference.
