Maintenance and operation of wind turbines

Maintenance and operation of wind turbines

Performing work to keep the wind turbine in usable state
1. Scheduled maintenance check in accordance with the manufacturer’s requirements
Scheduled maintenance check in accordance with the manufacturer’s requirements implies executing a certain list of works on a predetermined periodic basis to keep the trouble-free operation of the wind turbine. Each type of equipment has its own list of scheduled maintenance checks, which is subject to mandatory execution in order to keep warranty obligations for the wind generator.
2. Service work
The entire range of service works can be divided into 4 types: visual inspection, electrical service, mechanical service and lubrication.
Visual inspection
Visual inspection
Visual inspection, at first glance, seems to be a useless and simple stage of wind turbine maintenance. However, experts know that if the emerging small “irregularities” and “roughness” in the equipment operation are overlooked, if there is no due attention paid to the messages of the wind turbine automatic control system, a serious breakdown of the machine can be expected. Visual inspection is carried out not just by single-functioned workers, but by industry professionals who are fully responsible for the working efficiency of the turbine.

Lubrication work

Lubrication work is carried out to prevent excessive wear of mating surfaces, which include:

Installation of original oilers
Carrying out maintenance work on the lubrication system using original consumables
Replacing and filling the central lubrication system
Filling the central lubrication system with lubricants recommended by the manufacturer using specialized equipment
Performance testing
Testing the serviceability and correct functioning of the central lubrication system
3. Repair work
During the wind turbine operation, after a certain period of time, any owner is faced with the problem of repairing the wind turbine. The quality and efficiency of restoring the turbine's operability directly affects the generation of electricity by wind turbines and, accordingly, the company's income. For our part, we are ready to assist you in carrying out repair work of a wind generator of any complexity.
The following types of repair work performed by our specialists on an ongoing basis, will allow you to estimate qualifications and competence of our company:
  • Repair and replacement of failed elements and parts of the transformer substation equipment;
  • Restoration of boards and microchips of wind turbines, replacement of faulty components and parts;
  • Replacement of wind turbine generator bearings;
  • Restoration of the seat for the rotor bearing of the wind turbine generator;
  • Restoration of windings of the generator and damages of a lacquer covering;
  • Retightening of bolted joints of flanged joints with the required force;
  • Restoration of the braking system performance of wind turbines;
  • Restoration of the hydraulic systems performance of wind turbines;
  • Restoration of the seams tightness of the wind turbine nacelle body;
  • Alignment of motor shafts;
  • Endoscopic examination of the internal cavities of units and mechanisms
