Title: Voltage and Current Unbalance Compensation Using a Parallel Active Filter

Abstract

A three-phase insulated gate bipolar transistor (IGBT)-based parallel active filter is used for current and/or voltage unbalance compensation. An instantaneous power theory is adopted for real-time calculation and control. Three control schemes, current control, voltage control, and integrated control are proposed to compensate the unbalance of current, voltage, or both. The compensation results of the different control schemes in unbalance cases (load unbalance or voltage source unbalance) are compared and analyzed. The simulation and experimental results show that the control schemes can compensate the unbalance in load current or in the voltage source. Different compensation objectives can be achieved, i.e., balanced and unity power factor source current, balanced and regulated voltage, or both, by choosing appropriate control schemes.

  • A three-phase insulated gate bipolar transistor (IGBT)-based static var compensator (STATCOM) is used for voltage and/or current unbalance compensation.

  • This paper presents a new double-sided modulation strategy for matrix converters based upon an indirect conversion scheme which models the matrix converter as two independent stages performing rectification and inversion. The new modulation strategy keeps the number of switchings at a minimum. This paper shows that the indirect conversion scheme contains insufficient information to achieve the minimum. The new strategy establishes a link between the two modulations. Numerical simulations as well as analytical results show a reduction of more than 10% of the switchings compared to the conventional strategy. It is shown that the indirect conversion scheme is quite usefulmore » in the analysis of the input voltage unbalance. A feedforward compensation method based upon measurements of the instantaneous values of all three input voltages is presented. It is shown that with a further restriction on the voltage transfer ratio it is possible to operate the converter with balanced output voltages, even when input voltages are unbalanced.« less
  • A new input current modulation strategy for a matrix converter is presented. The performance of the new strategy during input voltage unbalance is compared to two other strategies. The difference of the three modulations only concerns the detection of the reference angle for the input current vector. The input current quality is evaluated using four different criteria. It is concluded that depending upon the modulation strategy, the distortion of the input current may appear either as a series of positive sequence harmonics or a negative sequence fundamental component or a positive and a negative series of harmonic components with reducedmore » amplitudes. Good accordance is found between the analytical solutions and numerical simulation.« less
  • In this paper design considerations for six pulse and twelve pulse diode rectifier systems operating under utility voltage unbalance and pre-existing harmonic voltage distortion is discussed. For a six pulse diode rectifier system it is shown that voltage unbalance and pre-existing voltage distortion in the utility generates uncharacteristic harmonics in the line currents. The amplitude of these uncharacteristic harmonics are shown to be amplified if the diode rectifier is operating in discontinuous conduction mode. For a twelve pulse diode rectifier system connected in parallel to feed a common dc link via interphase reactor it is shown that a small amountmore » of impedance mismatch, utility voltage unbalance or pre-existing voltage distortion drastically affects the current sharing capability of the rectifier bridges. This in turn generates additional uncharacteristic and characteristic harmonics thereby increasing the THD. In order to mitigate these effects and ensure proper operation of diode rectifiers, specially designed line reactors termed as Harmonic Blocking Reactors (HBR`s) are introduced. he analysis and design procedure for the HBR`s are discussed. Simulation results illustrate improved performance. Experimental results from a laboratory prototype system show close agreement with theory.« less
  • Indirect Current Control (ICC) of boost type Voltage Source Converters (VSCs) using separate compensation of line IZ voltage drop is presented. A separate bi-directional VSC is used to produce the compensation voltage. This simplifies the ICC regulator scheme as the power flow is controlled through single modulation index. Experimental verification is provided for bi-directional control of the power flow.
