Output Voltage and Current Ripples performance Examination in Two Bus system with Boost converters fed UPQC and reduction

This paper presents UPQC with various Boost converter device for reduce the receiving end voltage and sending end current ripples of existed conventional multi bus system. Unified Power Quality Conditioner (UPQC) is a dynamic FACT device transmission system. The UPQC configuration has the capabilities of these two devices, Voltage Regulators, Active Filters. It is noticed that the multi bus system with UPQC minimises the system losses. So UPQC increases the multi bus system performance. This paper also presents the suitable boost converter between PV system and UPQC capacitor to charge the capacitor. Here principle of operation and its implementation of boost converters for multi bus system are presented. Three various types of boost converters those are High Step Up type Boost Converter (HSBC), Double Inductor type Boost Converter (DIBC) and Inter Connected Boost Converter (ICBC) are used for comparative analysis. The comparison is done in boost converter output voltage, input current and those ripples, also transmitting real power and reactive powers. With MATLAB/SIMULINK results, Inter Connected Boost Converter (ICBC) is selected as best converter device in between Photo voltaic system, capacitor of UPQC.
