Enhancing Fault Ride Through The Capability Of A Grid-Connected Pmsg-Based Wind Energy Conversion System

Abstract

In Response To The Growing Need For Additional Electricity Beyond Traditional Energy Sources, The Significance Of Harnessing Renewable Energy Sources Has Greatly Increased Worldwide. From These Sources, Wind Energy Conversion Systems Have Become The Primary Contributors To Power Generation Systems. Due To The Escalating Severity Of Global Environmental And Climate Issues And The Rapid Rise In Fuel Costs And Electricity Demand, The Renewable Energy Source, Wind Energy, This Has Become One Of The Most Speedily Expanding Energy Sources. A PMSG Is A Crucial Generator That Is Used In Wind Energy Conversion Systems, Including Machine Side And Grid Side Converters Using PI Controllerconnected To The Grid Systems. The Production Of Wind Farms Experiences Fluctuations Due To The Irregular Nature Of Wind Speeds. Also Due To Nature And Unnatural Three-Phase Faultshappened In Wind Turbines Linked To The Grid. This Will Cause The Generator To Produce An Unbalanced Three-Phase Voltage And Current. During Normal Operation 690 V Generated From PMSG. This 690 V AC Converted To 690 V DC By Using Rectifier. Again This 690V DC Voltage Is Converted To 690 V AC And By Using Two Step-Up Transformers This Voltage Is Updated To 230 Kv. The Grid Voltage Is 230KV And When L-G, 2L-G 3L-G Types Of Fault Happened To The System, Voltage From The Grid Is Minimized To Around 200 Kv, 150 Kv, And 80 Kv Respectively. These Deviations, In Turn, Give Rise To A System Stability Issue Caused By The Violation Of The Voltage. So, Fault Ride-Through Capability Is Very Necessary For The Stability Of Power Generation Plants. To Overcome These Different Types Of Faults In The Power System STATCOM PI Controller Is Designed. This STATCOM Returns The Voltage To Normal Operation (230 Kv) By Injecting And Absorbing Reactive Power. The Simulation Of Voltage Control PMSG Has Been Designed On MATLAB/Simulink Software.
