Simplified P &O MPPT Algorithm Based Performance Analysis and Control of Three-Phase IIG-Based MHPCS for Remote Single-Phase Household Applications
摘要
This paper introduces a Simplified Perturb and Observe algorithm for constant voltage and frequency operation of a three-phase Isolated Induction Generator (IIG) coupled to an ungoverned hydro turbine and supplying single-phase domestic loads. With a fixed excitation capacitor bank connected across the stator terminals, the IIG simultaneously supplies power to both ac load (main load) and controlled dc load (dump load). The output power of the generator is always maintained constant at its maximum value corresponding to the capacitor bank. The main advantage is that the developed algorithm not only tracks the maximum output power point of the generator but also diverts power smoothly from main load to dump load and vice-versa to maintain the voltage and frequency at constant value. An excitation scheme of three-phase IIG including two capacitors (
