SyncWind 's Synchronous Power-train

Our cost-effective, patented, proven system enables turbine speed to vary
while the synchronous generator runs at constant speed:
No power electronics, type 5 grid connection at type 3 cost.

 

SyncWind. will work with wind farm owners, wind turbine manufacturers and/or power-train suppliers who are at the forefront of wind energy and interested to utilise SyncWind.’s proven power-train technology at multi-MW or mid-size scale.

Low Cost of Energy

SyncWind.’s synchronous power-train is cost-effective, because it eliminates the need for power electronic converters (PECs). PECs are rated at either 100% of the turbine rated power (Type 4), or a large (30-40) percentage (Type 3). Either way they are a significant capital cost. PECs are also known causes of maintenance costs, seldom lasting 10 years in the field.

By contrast SyncWind.’s proven power-train technology incorporates a small hydraulic sub-system, which is rated at only 5% of turbine rated power. Remarkably the new, patented “low variable-speed” (LVS) system enables broad-band variable speed while keeping the hydraulics at only 5% of turbine rated power. Thus it can address the global wind power market which is dominated by lower wind speed sites than those found in New Zealand and Scotland. This is the key to its cost-effectiveness. The following table illustrates how this will result in lower turbine cost relative to the least-cost (Type 3) turbines available, and lower wind farm cost.

No Power Electronics (PEC)  =  Lower Overall Power-Train Cost  =  Lower Turbine Cost

No Power Electronics = Lower Overall Power-Train Cost = Lower Turbine Cost

No PECs, SVCs, Sync-cons*, DVARs* =  Lower wind farm cost  =  Much lower COE*

  • Power-train costs are lower (per above table)

  • O&M costs are lower (no PECs)

  • No need for auxiliary services equipment for grid connection
    (Sync-cons*, DVARs*, etc.)

Thus lower overall societal cost of renewable future due to:

  • lower turbine cost (because of power-train capital + O&M cost savings)

  • lower wind farm auxiliary costs

  • larger wind farm potential/less curtailment

* ... Sync-con  =  synchronous condenser
* ... DVAR  =  dynamic VAR controller
* ... COE  =  cost of energy

The wind industry can avoid upcoming costly additions to electrical systems ...

Grid stability with renewables? Yes, Wind can!

Top

SyncWind.s power-train enables its synchronous generator to be directly connected to the grid, providing physical inertia for grid stability the same as traditional power generators, without power electronics.  For information on SyncWindi's provided grid stability, please see our article "Grid stability with renewables? Yes, Wind can! - SyncWindi’s power-train and its synchronous generator provide physical inertia for grid stability".

Synchronous wind power is proven and cost-effective. Synchronous generators enhance system security, reliability and resilience. Physical inertia and large amounts of fault current are two attributes, in terms of which systems with PECs cannot compete with synchronous generators. So wind power will cost less and be better for grids – why wouldn’t the industry opt for synchronous wind turbines?
