Modeling of 11-Level Cascade Multilevel STATCOM
This paper presents analytical approach for modeling of 11-level cascade multilevel STATCOM connected to power system for voltage regulation applications. A technique based on energy equivalence is proposed for computation of equivalent capacitance which represents true value of variable structure of capacitances connected in individual H-bridges. The necessity of equivalent capacitor is an ess...
متن کاملA Novel Controller Based on Single-Phase Instantaneous p-q Power Theory for a Cascaded PWM Transformer-less STATCOM for Voltage Regulation
In this paper, dynamic performance of a transformerless cascaded PWM static synchronous shunt compensator (STATCOM) based on a novel control scheme is investigated for bus voltage regulation in a 6.6kV distribution system. The transformerless STATCOM consists of a thirteen-level cascaded H-bridge inverter, in which each voltage source H-bridge inverter should be equipped with a floating and iso...
متن کاملAnalysis of the Discontinuous Pwm Controlled D-statcom for Reactive Power Compensation Applications
Original scientific paper The scope of this paper covers the investigations of discontinuous PWM (DPWM) control of the Distribution Static Synchronous Compensator (D-STATCOM). Various DPWM methods have been widely used in motor drives for controlling the inverter and reducing power losses. With the rising demand for energy, energy efficiency has currently become an issue of vital importance. As...
متن کاملDSP-controlled, space-vector PWM, current source converter for STATCOM application
Basic operational concepts of the single current source converter (CSC)-based STATCOM are studied in this paper. The space vector modulation scheme is adopted to control switching functions of the CSC. Capitalizing on anticipated new switch technology, the reduced-size LC filter is examined and design guidance is given. A filter current compensation method to reduce the error between command an...
متن کاملRedundancies in Transformerless Network Synthesis
Abstract— The purpose of this paper is to give a compact summary of recent results based on the concept of a regular positive-real function. We will list an efficient set of networks which is capable of realising all biquadratics which are realisable by 5-element networks or 6-element networks of seriesparallel type. The structures are simpler than the full BottDuffin synthesis, though there ar...
