Power factor correction and harmonics mitigation based on phase shifting approach

D. D. Reljić; V. V. Vasić; Dj. V. Oros 2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC), 2012

The traditional approach to power factor correction in industrial applications involves installation of capacitor banks. But, with the widespread use of non- linear loads, such as variable speed drives (VSDs), power factor improvement has become more difficult. The presence of harmonic currents cause power capacitors to absorb them, as capacitor impedance is inversely proportional to frequency. The effects are overheating ...

  • Impedance Source Inverters

    The Z???source/quasi???Z???source inverter (ZSI/qZSI), so called impedance source inverter, has attracted increasing interests due to a single???stage power conversion with step up/down function, handling the DC voltage variations in a wide range without overrating the inverter, and allowing the switches on the same bridge leg turn on together. All of these can minimize system cost, reduce component count and cost, and improve system reliability. The operation principle and control methods of conventional ZSI/qZSI are presented. Also, the advantages and control of novel extended topologies, such as qZSI with Battery and qZSI based cascade multilevel systems are discussed. Impedance parameter design is addressed in detailed. This chapter offers a comprehensive and systematic reference for the future development of the high performance ZSI/qZSI.

  • Control and Protection of MMC¿¿?HVDC under AC and DC Network Fault Contingencies

    The modular multilevel converter (MMC) has become the most attractive voltage source converter (VSC) topology for high¿¿?power applications. AC or dc short¿¿?circuit fault conditions cannot be avoided in high¿¿?voltage direct current (HVDC) schemes, independent of the converter and the transmission link technology (e.g. cables or overhead lines). The probability, frequency, and characteristics of these faults depend on the employed transmission technology, converter technology (e.g. two¿¿?level or MMC), and the grounding topology (e.g. direct, resistive, or high¿¿?impedance). This chapter presents and compares the two¿¿?level VSC¿¿?HVDC and MMC¿¿?HVDC fault characteristics and behaviors under ac and dc fault conditions. It discusses the impacts of different component failures, and presents related control and protection techniques. VSC¿¿?HVDC terminals are designed to fulfill FRT requirements and remain synchronously connected to the network and provide the required ancillary services during the unbalanced ac fault conditions. Different techniques are applied to detect and protect the converter components from ac and dc fault conditions.

  • Transformers and Reactors

    This chapter discusses the basic transformer design and construction and explores primary and secondary values of voltage, current, and impedance through the transformer turns ratio. The modern power plant requires an internal electrical distribution system to operate all the auxiliary functions needed for reliable operation of the power plant. There are two main types of transformers in the industry based on their construction. The first type is the oil???filled transformer. The second type is known as a dry type. Transformers that are either fed from or feed vacuum circuit breakers or transformers that have the source??? or load???side conductors exposed to potential lightning may experience very high values of (di/dt) in their application. In a power generation facility that utilizes a secondary or primary selective system where sources can be paralleled, it is critical to get the phase relationships correct between electrical buses.

  • Typical Transformer-Based Z-Source/Quasi-Z-Source Inverters

    This chapter discusses the typical trans and LCCT Z-source/quasi-Z-source inverters (ZSIs/qZSIs). Their configurations, working operations, voltage and current principles, and simulation results are presented, providing a demonstration of the investigation of other extended transformer-based ZSIs/qZSIs. The two DC current blocking capacitors connected in series with the transformer also prevent the transformer core from saturating. The only difference is the charging/discharging of magnetizing inductance in the trans-Z-source inverter, rather than discrete inductances found in the conventional Z-source inverter. They showed improved performance compared to the basic ZSI/qZSI in terms of reduced element counts, compact passive components, and high voltage boosting ability. The unique topology of the LCCT passive input circuit also helped to prevent the transformer core from saturating. Also, by using high switching frequency power devices, such as silicon carbide (SiC) transistors and SiC diodes, high power density is expected for those transformer-based derivations of ZSI/qZSI.
