According to the World Bank, roughly 40 percent of residences in India are without electricity, and blackouts are a common occurrence throughout the country’s main cities. To address this shortfall, the Indian government has established an ambitious “Power for All by 2012” plan that will require the country’s installed generation capacity to grow from 140,000 megawatts (MW) to nearly 225,000 MW by 2012. It also will require billions of dollars of investment in India’s transmission and distribution infrastructure.

According to the Global Wind Energy Council’s Global Wind 2008 Report, India now ranks fifth in the world in terms of total installed wind power capacity. Capacity in the country grew by 22 percent in 2008 to 9,600 MW. The Indian Wind Energy Association estimates that the country has 65,000 MW of wind power potential.

AMSC’s first two wind turbine manufacturing customers in India are Ghodawat Energy Limited and Inox Wind Limited. Both licensed AMSC Windtec™ turbine designs within the past 18 months. AMSC, which is the exclusive power electronic system supplier for all Ghodawat and Inox wind turbines, announced today that it has received initial orders for five wind turbine electrical systems from Ghodawat and three wind turbine electrical systems from Inox.

Ghodawat, based in Kolhapur in the state of Maharashtra, India, will use the electrical systems for its initial production of 1.65 MW wind turbines designed by AMSC Windtec. Ghodawat, in collaboration with AMSC Windtec and AMSC India, has successfully erected and tested its first reference 1.65 MW wind turbine.

Wind Energy Market

Wind energy has emerged as the fastest growing source of energy, with 120 GW installed throughout the world at the end of 2008 according to the Global Wind Energy Council (GWEC). They project that the total cumulative worldwide capacity could exceed 1,000 GW by 2020. As the total base of installed wind capacity continues to grow with the installation of additional wind turbines and wind farms, compliance with interconnection criteria becomes increasingly important. In many cases, dynamic voltage regulation and continuous power factor correction are required to keep wind turbine generators online, assuring that the business interests and reliability expectations of both wind developers and utilities are met.

Technical challenges

Developers, operators, and utilities face many challenges when interconnecting large, distributed sources of generation with fluctuating output, such as wind energy. These challenges come in many forms.

Many of today’s wind turbines are induction type generators that absorb large amounts of VARs (Volt-Amperes Reactive) from the grid. For such machines, VAR flow fluctuates with the power output of the turbines. Uncompensated, these variations in VAR flow can cause severe voltage fluctuations, affecting overall power quality and the reliability of the local transmission grid. Traditionally, switched capacitors have been used to compensate for fluctuating VAR requirements. However, a typical wind farm can experience 50-100 capacitor switching events on a given day. Such frequent switching can cause stresses, effectively reducing life-cycle times of the capacitor switches. In addition, some wind generator gearboxes are sensitive to large step changes in voltage associated with normal capacitor switching, which can overstress the gearbox – one of the costliest and most maintenance intensive components of a wind turbine.

Keeping wind turbines online under low voltage conditions is also a potential trouble spot that developers and operators need to consider. Transient voltage events that drop voltage below turbine tolerance levels can cause generators to trip offline. Most interconnection standards today require wind farms to have the ability to ride through faults (Low Voltage Ride Through). This can be accomplished either by the wind turbine manufacturer or with a centralized solution in the wind farm substation.

D-VAR® Systems

AMSC’s D-VAR system is ideally suited to help meet wind farm interconnection standards. The D-VAR system is a fully integrated, inverter-based reactive compensation system (STATCOM). It can be seamlessly integrated with low cost capacitor banks in an extremely cost-effective solution that provides steady-state voltage regulation, power factor correction, and high and low voltage ride through capability for the entire wind farm. The D-VAR system can also “soft-switch” capacitors, thereby eliminating the voltage step changes seen by the wind farm and the utility.

D-VAR systems are cost effective solutions that can provide tight voltage regulation and power factor correction to alleviate fluctuating voltage and VAR demands at wind farms.

AMSC’ s newest dynamic reactive power product is the D-VAR RT system designed to enable individual wind turbines to meet even the most restrictive grid interconnection requirements. This patent-pending product brings a powerful solution to operators of existing wind turbines that are facing challenges due to new regulatory requirements, such as the Spanish grid interconnection requirement P.O.12.3.

The D-VAR RT in-turbine system is a powerful, cost-effective technology that dynamically stabilizes the wind turbines and also can regulate the voltage of the collection system connecting to the power transmission grid. Problems solved by the D-VAR RT system include voltage regulation, power factor correction and low- and high-voltage ride through.
PowerModule™ Power Converters

The AMSC PowerModule PM1000 is a power converter designed with a building block approach that can be placed right in the wind turbine. The PM1000 inverter can provide power flow control and low voltage ride through (LVRT) capability, similar to the external D-VAR solution, and is cost effective for smaller wind farms. It is a highly power dense (130 W/ in3), fully programmable, flexible and modular system and can be applied to various wind turbine makes and models.
