Performance Analysis of Fuel Cell DSTATCOM

摘要

The application of Fuel Cell Interfaced Distribution STATic COMpensator (DSTATCOM) for active and reactive power interaction along with harmonic elimination has been discussed in this paper. The energy interfaced DSTATCOM can be used for (i) Harmonic Elimination, (ii) Load Balancing, (iii)Reactive Power Compensation and (iv) Active Power supportduring peak load period. This paper investigates the effectiveness of performance of Fuel Cell interfaced DSTATCOM and analyses the effectiveness of control law and controllers for Power Quality enhancement. The electrical equivalent model is integrated with the DSTATCOM to study the capability to absorb/supply active power at the DC bus. The control scheme for fuel cell interfaced DSTATCOM is developed to produce the reference currentsi*_fx for the current controlled Voltage Source Converter (VSC), which will inject current at the Point of Common Coupling (PCC)to eliminate harmonics and maintain the PCC voltage while supplying a part of active power demanded by the load. This ensures the source current to be balanced and single frequency. The transient simulationis performed on anelaborated nonlinear model of DSTATCOM/Fuel Cell system using MATLAB-SIMULINK toolto validate the satisfactory response of DSTATCOM.
