  1. 1. REACTIVE POWER COMPENSATION USING STATCOM<br />SANDEEP A S<br />10EE61R11<br />IIT KGP<br />
  2. 2. VARIOUS COMPENSATION SCHEME <br />SHUNT CAPACITOR<br />SYNCHRONOUS CONDENSOR<br />SVC<br />STATCOM<br />
  3. 3. ADVANTAGES OF STATCOM <br /><ul><li>FAST RESPONSE
  4. 4. COMPENSATION FOR LAGGING AND LEADING VAR
  5. 5. HARMONIC ELIMINATION</li></li></ul><li>OPERATING PRINCIPLE<br />
  6. 6. CONTROL STRATEGIES<br /><ul><li> VARIABLE VOLTAGE
  7. 7. PHASE ANGLE CONTROL WITH CONSTANT Vdc</li></li></ul><li>SIMULATION CIRCUIT<br />
