GW140 3S – Benefiting from the scalability and adaptability of the 2.5 MW PMDD platform

Goldwind has been innovating for a brighter energy future for more than two decades. The GW140 3S Smart Wind Turbine PMDD platform is part of that innovative future. The design principles of the Goldwind GW140 3S and the Goldwind 2.5MW remain much the same. The new GW140 3S introduces best-in-class energy production, smarter controls and industry-leading reliability.

Scalable capacity. Through the scalable nature of the GW140 3S platform, the rated output of the turbine can be scaled from 3.0MW to 3.4MW with a rotor diameter up to 140 metres. As a result of the adaptive nature of the GW140 3S platform for low and ultra-low wind speeds, the turbine can be extensively applied to projects with average wind speeds ranging from 5.5 to 8.5 m/s.

Scalable rated power and group control systems are two key elements for maximum energy production. With these two site-adaptive technologies combined, turbines synchronise closely with each other to compensate for any loss in total power output. The two technologies can also be utilised for decreasing noise emissions, to operate in special wind conditions, harsh terrain and extreme high/low temperatures.

Smart sensing. The GW140 3S platform’s key components are monitored by multiple strategic sensors that enable predictive diagnostics and precision control.

Smart control. Based on Goldwind’s big data analysis of tens of thousands of installed direct-drive turbines and more than 20 years of wind energy expertise, Goldwind has partnered with Det Norske Veritas and Germanischer Lloyd (DNV-GL) and Energy research Centre of the Netherlands (ECN) to develop the most advanced optimised control algorithms for maximum energy capture.

Structured design. In addition to Goldwind’s overall optimised design features for unique operating conditions, the GW140 3S’ modular approach features shared blade molds, a single blade erection method, and modular generator technology – all of which support efficiencies in logistics, installation, operations and maintenance over the life of the turbine.

Double-circuit design. Goldwind’s double-circuit design architecture for the GW140 3S PMDD generator enables continued limited operation in the event of a circuit failure until a service technician is able to perform repairs. This partial power output approach results in more energy capture for the customer during periods in which the turbine would otherwise be out of service.
