Classic Fleet

Over the last two decades, we have built a range of turbines that generate 600 KW to2100 KW. These turbines continue to generate power across the world, supported by our services. While we no longer manufacture turbines from our classic fleet, we continue to offer maintenance to ensure that our customers’ assets run smoothly. This has enabled us to reach achievements such as 20 years of successful operation at our Dhank wind farm.

We continue to maintain and ensure performance of all turbines supplied by us and are covered by service agreements.

S88-2.1 MW

With the introduction of new, high-yield next generation wind turbines, Suzlon has phased out its older WTG models viz. S88, S82, S66, and S52. We however, continue to support, operate and maintain all our installed wind turbines.

The S88-2.1 MW is designed for a medium wind speed regime. The wind turbine concept is based on a robust design with pitch regulated blade operation, a three-stage gearbox with 2,310 kW rating and flexible coupling to the asynchronous induction generator. The Suzlon flexi-slip system provides efficient control of the load and power control while the turbine operation is effectively managed by the Suzlon controller. These technologies are all well known in the wind power industry and have proven themselves. The S88-2.1 MW is designed to withstand extreme conditions and operate effectively with low maintenance costs.

As with all other Suzlon blades, the AE43 is a fully integrated design. The blade manufacturing system, from mold engineering to state-of-the-art Resin Infusion Molding (RIM), is implemented in close co-operation between the Dutch design team and the manufacturing plant operators. The S88 blades are manufactured in our Dhule, Rotor Blade Unit Chaddvel.

The full-span blade pitching system is based on electrical motors with individual power backups which allow fast and efficient pitching of the blades. With a resolution of 0.1° and a special fast-pitching mode, the S88-2.1 MW allows optimal power output as well as fast and safe braking of the rotor.

Suzlon has always placed significant focus on gearbox design. The design philosophy is based on years of experience with wind turbines in harsh environments and our internal design standards exceeding those of the industry. The power rating of the Winergy gearbox for the S88-2.1 MW is actually 2,310 kW. To know more about this product, click here to download product brochure.

S82-1.5 MW

With the introduction of new, high-yield next generation wind turbines, Suzlon has phased out its older WTG models viz. S88, S82, S66, and S52. We however, continue to support, operate and maintain all our installed wind turbines.

The S82-1.5 MW is designed for generating optimal power output even at sites with a modest wind speed regime.

S82-1.5 MW is equipped with an asynchronous generator with high slip; it can operate within a limited speed range. In conjunction with the pitch system it is possible to achieve an optimal energy yield within a wide wind range, with comparably low loads.

Once the starting speed is reached, the turbine speed is controlled by the pitch system so that it comes as close as possible to the synchronous speed of the generator. The generator is connected to the grid by means of a soft starter with thyristors. To accomplish this, no motor start is required. In case of slow and mean wind speeds, the blades are positioned at an optimal angle in order to achieve an optimal yield.

Once the nominal speed has been reached (cut-in completed; bypass contractor closed), the pitch system starts operating in order to maintain the rated power. The slip of the generator is big enough to react to minimize the load during wind gusts, thus ensuring a constant output of power.

As anemometers and wind vanes are provided on the nacelle roof, the rotor and the nacelle exert an influence on the measurement of the wind speed and direction. This influence is known and will be balanced by the controller so that it is possible to work with this data without any problem.

The control is extremely robust in order to operate under stringent environmental conditions when used in a wind turbine. Under these conditions, all standard solutions would very quickly reach their limits. The controller has therefore been especially developed for use in Suzlon wind turbines.

S66-1.25 MW

With the introduction of new, high-yield next generation wind turbines, Suzlon has phased out its older WTG models viz. S88, S82, S66, and S52. We however, continue to support, operate and maintain all our installed wind turbines.

The S66-1.25 MW is designed for generating the optimal power output even at sites with a modest wind speed regime.

S66-1.25 MW is equipped with a dual speed, dual rating asynchronous generator; it can operate within a limited speed range. In conjunction with the pitch system, it is possible to achieve an optimal energy yield within a wide wind range, with comparably low loads.

Once the starting speed is reached, the turbine speed is controlled by the pitch system so that it comes as close as possible to the synchronous speed of the generator. The generator is connected to the grid by means of a soft starter with thyristors. To accomplish this, no motor start is required. In case of slow and mean wind speeds, a small rating generator is connected to the grid.

Once the nominal speed has been reached (cut-in completed; bypass contractor closed), the pitch system starts operating in order to maintain the rated power. The generator is coupled through a fluid coupling to react to minimize the load during wind gusts thus ensuring a constant output of power.

As anemometers and wind vanes are provided on the nacelle roof, the rotor and the nacelle exert an influence on the measurement of the wind speed and direction. This influence is known and will be balanced by the controller, so that it is possible to work with this data without any problem.

The control is extremely robust in order to operate under stringent environmental conditions when used in a wind turbine. Under these conditions, all standard solutions would very quickly reach their limits. The controller has therefore been especially developed for use in Suzlon wind turbines.
