  WAMS Based Equivalent Inertia Computation of Wind Turbine Generators under Faults/Disturbances Preamble: 1.   Introduction 2.   Objective 3.   Literature 4.   Scope of Work 5.   Salient Features of Proposed Tool 6.   Deliverables  7.   Funding Requirement 8.   Collaboration with third parties 9.   Conclusion & Future Scope 1.   Introduction Presently, India has an installed power generation capacity of 253.4 GWs (As on 31/08/2014), of which renewables account for about 31.7 GW, and wind makes (66.67 %) up a majority of this installed capacity. Historically, the States of Tamil Nadu, Karnataka, Maharashtra and Gujarat have been the leaders in terms of total wind installations. The States of Rajasthan, Madhya Pradesh and Kerala are quickly catching up. In terestingly more than 95 percent of the nation’s wind  energy development to date is concentrated in just five states in Southern and Western India  –  Tamil Nadu, Andhra Pradesh, Karnataka, Maharashtra and Gujarat. These five  states accounted for over 85% of the total installed capacity at the end of the last plan period. Rajasthan is another emerging State with rising wind turbine installations. The 12 th  Plan envisions installing 100 GW of new capacity of which 30 GW is projected to come from renewable energy Sources, of which wind would account for 15 GW. Historically the Indian wind energy sector has met and occasionally exceeded its allocated target. The state-wise renewable Purchase Specification (RPS) targets and the tradable renewable energy Certificates (REC) provide further support for the sector. Often inadequate and weak grids act as a barrier to smoother integration of power generation from renewables. The variability of wind power can create problems for the traditional grids in maintaining a supply and demand balance. Renewable energy generation further complicates the process of evacuation and dispatch. According to the norms laid down in the 2010 Grid Code (IEGC), wind power generators are responsible for forecasting their daily generation with accuracy up to 70%. Only in the event of generation being ±30% of the scheduled the wind generator will have to bear the unscheduled interchange (UI) charges. With continuously rising wind power penetration in the grid, wind power generators will have to work together with grid operators and electricity distribution companies to address issues related to grid stability and power quality in the immediate future. Wind Power being source of energy is variable in nature. Variable output from wind power impact grid operations, in the same way grid disturbances affect the behavior of wind power plants. Increasing penetration of wind generation demands scrutiny of every aspect related to wind plant operations. Recently around 60 PMUs installed all over Indian grid through pilot project. However the PMU applications for operating power system are not yet fully utilized. The availability of synchronized time stamped phasor data from PMUs at wind power plants offers great opportunities in exploring and understanding wind power plant operations during normal and contingency conditions. Other important aspect is that Sub Synchronous Resonance (SSR) phenomenon can be detected and its influence can be monitored at wind power plants. Objective:
