Design, control and application of modular multilevel by Kamran Sharifabadi, Lennart Harnefors, Hans-Peter Nee,

By Kamran Sharifabadi, Lennart Harnefors, Hans-Peter Nee, Staffan Norrga, Remus Teodorescu

Design, keep an eye on and alertness of Modular Multilevel Converters for HVDC Transmission Systems is a complete consultant to semiconductor applied sciences appropriate for MMC layout, part sizing keep an eye on, modulation, and alertness of the MMC know-how for HVDC transmission.

Separated into 3 targeted elements, the 1st bargains an outline of MMC expertise, together with info on converter part sizing, keep watch over and conversation, defense and Fault administration, and popular Modelling and Simulation. the second one covers the purposes of MMC in offshore WPP, together with making plans, technical and fiscal standards and optimization ideas, fault administration, dynamic and temporary balance. ultimately, the 3rd bankruptcy explores the purposes of MMC in HVDC transmission and Multi Terminal configurations, together with Supergrids.

Key features:

  • Unique assurance of the offshore program and optimization of MMC-HVDC schemes for the export of offshore wind strength to the mainland.
  • Comprehensive rationalization of MMC software in HVDC and MTDC transmission technology.
  • Detailed description of MMC elements, regulate and modulation, diversified modeling techniques, converter dynamics less than steady-state and fault contingencies together with software and housing of MMC in HVDC schemes for onshore and offshore.
  • Analysis of DC fault detection and safeguard applied sciences, approach stories required for the mixing of HVDC terminals to offshore wind energy crops, and commissioning systems for onshore and offshore HVDC terminals.
  • A set of self-explanatory simulation versions for HVDC attempt instances is obtainable to obtain from the better half website.

This ebook presents crucial examining for graduate scholars and researchers, in addition to box engineers and execs who require an in-depth knowing of MMC technology.

Sample text

In this case the capacitors have no connection to a common dc link, and are therefore referred to as flying capacitors. 10 shows the different switching states of a three-level phase leg for the case where the ac-side current is directed out of the ac terminal at the midpoint of the phase leg. The voltage of the flying capacitor should be maintained at half of the pole-to-pole dc-side voltage (which is Vd ). As evident from the figure, two of the states are again identical to the switching states of the ordinary two-level phase leg.

These topologies are also characterized by having diodes (called clamping diodes) providing additional paths for the current so that the ac terminal can be temporarily connected to these dc levels during operation. Thus, the creation of additional ac voltage levels is made possible. The three-level variant is referred to as a neutral point clamped (NPC) converter since the clamping diodes in this case can link the ac terminal to the midpoint (which may be of neutral potential) of the dc link. This was also the name used in [1] which did not cover the extension to more than three levels.

The external circuits on the ac and dc sides are modeled in such a way so as to allow for common-mode as well as differential-mode voltages and currents on both sides. 17 Simplified equivalent schematic of an MMC. Submodule strings depicted as controllable voltage sources. 19) iu???? + il???? . 2 A physical interpretation of these quantities is that is???? are the ac-side phase currents and ????s???? the inner emf (electromotive force) of each phase leg driving these currents. Correspondingly, ic???? are the average currents of each phase leg, whereas ????c???? are the voltages driving these currents.
