What failures can occur in wind turbines? The importance of oil testing

Wind power paves the way for a green future, but it also presents challenges for wind farm owners and operators. Today, availability has become more important, and the cost, size, complexity and operational demands of drive components have also increased. Preventive maintenance has become the single most important controllable factor in achieving profitability, and there is no doubt that condition monitoring plays an integral role.

(1)Reducing unplanned maintenance is the key to reducing O&M costs: 58% of total operating expenses are O&M-related, 64% are due to unplanned maintenance

Wind turbines include key mechanical components such as turbine blades and rotors, drive trains and generators.

Their cost accounts for more than 30% of the total capital expenditure for offshore wind projects. In general, wind turbines are intended for use in relatively inaccessible locations, imposing some constraints on the design in a number of ways. For an offshore environment, the site can actually be visited once a year for maintenance. Therefore, the fault tolerance of wind turbines is of great significance for the development of wind farms.

Yateks oil analysis instrument: comprehensive YOT oil analyzer, multi-function iron mass, oil spectrometer. These devices can provide detection.

(2)One of the key components of a wind turbine is its drive train, which connects the pneumatic rotor to the electrical output terminals. The optimization of wind turbine generators cannot be achieved without considering the mechanical, structural, hydraulic and magnetic properties of the drive train. Generally speaking, they can be divided into four types according to their structure:

Conventional: gearbox and high-speed generator with few pole pairs;

Direct drive: any drivetrain without a gearbox and a multi-pole pair of low-speed generators;

Hybrid: Any drive train with a gearbox with a generator speed between the two types above;

Multiple generators: any drive train with more than one generator;

Metal abrasive sensor OR online monitoring system (YTS61+YFM) can solve these problems.

(3)Another core component of a wind turbine is its generator.

Traditionally, there are three main types of wind turbine generators (WTGs) used in various wind turbine systems, which are direct current (DC), alternating current (AC) synchronous generators and alternating current asynchronous generators.

Yateks online monitoring system (YTS61+YFM) has these functions.

  1. Saving potential using the example of a gearbox on a wind turbine

(1)Cost factors of a gearbox: >194000 €

(2)A new gearbox costs approx. 160,000 €

The delivery time for a new gearbox is approx. 6 months

  1. A mobile crane causing the following costs is needed to replace the gearbox

(1)Transport of the crane to the wind turbine: approx. 30,000 €

(2)Daily user costs: 4,000 €

  1. Cost advantages when using Condition Monitoring Systems:

(1)Damage can be detected in good time

(2)Repair costs are considerably lower than replacement costs

(3)Repairs on the nacelle can be carried out at an early stage.
