This book was released on 2020-12-31 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of large-scale renewable generation and load electrification call for highly efficient and flexible electric power integration, transmission and interconnection. High Voltage DC (HVDC) transmission technology has been recognized as the key technology for this scenario. HVDC transmissions, including both the line commutated converter (LCC) HVDC and voltage source converter (VSC) HVDC have played an important role in the modern electric power system. However, with the inclusion of power electronic devices, HVDC introduces the characteristics of nonlinearity and different timescales into the traditional electromechanical system and thus careful modeling and simulation of HVDC transmission are essential for power system design, commissioning, operation and maintenance.

Download or read book Modular Multilevel Converter Modelling and Simulation for HVDC Systems written by Davide del Giudice and published by Springer Nature. This book was released on 2022-10-21 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive review of the models and approaches that can be employed to simulate modular multilevel converters (MMCs). Each solution is described in terms of operating principle, fields of applicability, advantages, and limitations. In addition, this work proposes a novel and efficient simulation approach for MMCs based on sub-circuit isomorphism. This technique, which has its roots in the electronics fields, can be profitably exploited to simulate MMCs regardless of the model used to describe its sub-modules, including the most accurate ones. Lastly, this book considers a well-known high voltage direct current (HVDC) benchmark system consisting of two MMCs. After describing the implementation details of each benchmark component, simulation results in several scenarios (ranging from normal operating conditions to faults in the AC and DC grid) are included to validate the proposed approach and showcase its key features. Due to its educational content, this book constitutes a useful guide for PhD students and researchers interested in the topic of MMCs and their simulation. It also serves as a starting platform for junior electrical engineers who work in the field of power electronic converters for HVDC systems.
Book Synopsis Dynamics and Control of VSC-based HVDC Systems by : Rodrigo Teixeira Pinto
Download or read book Dynamics and Control of VSC-based HVDC Systems written by Rodrigo Teixeira Pinto and published by LAP Lambert Academic Publishing. This book was released on 2012-05 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electricity transmission began with direct current. In 1880, Edison patented the first DC distribution system. That DC system was vital to broaden the use of his most famous invention, the electric lamp. However, at that time, low-voltage DC was proven inefficient. Despite the success of AC systems, the efforts for the development of practical high-voltage direct current transmission (HVDC) continued. The first HVDC transmission system was built in Sweden, in 1954, using mercury-arc valves. Nowadays, modern voltage-source converters (VSC) have smaller space requirements and improved reliability. VSC-HVDC has brought back the interest in the establishment of DC networks for applications such as DC supergrids and transnational networks for offshore wind farms. The goal of this work is to develop a more straightforward simulation model of VSC-HVDC systems; which can be inputted into simulation software packages and still provide realistic and reliable data on the system operation under all circumstances. The major contribution is the integration of the developed model, representing the whole DC transmission link, with the manifold control strategies possible for this new technology.

Book Synopsis Extended-frequency Dynamic Phasor Modelling of LCC-HVDC Systems for Electromagnetic Transient Simulations by : Afshin Bagheri Vandaei
Download or read book Extended-frequency Dynamic Phasor Modelling of LCC-HVDC Systems for Electromagnetic Transient Simulations written by Afshin Bagheri Vandaei and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new model for line-commutated converter (LCC) HVDC systems based upon the concept of extended-frequency dynamic phasors is developed in an electromagnetic transient (EMT)-based simulation platform. The proposed model is capable of representing LCC-HVDC converters during normal as well as abnormal operating modes, such as system imbalances and commutation failure, by automatically adjusting its parameters based upon converter terminal quantity measurements. The model offers a high level of accuracy with reduced computational burden as a suitable replacement for conventional switch-based models of LCC in EMT simulation platforms. The proposed model is then extended to real-time EMT simulations. The performance of the proposed model is first evaluated against detailed EMT simulations of a simple LCC system. The evaluation is then extended to simulation of large electric networks such as CIGRE HVDC benchmark and IEEE 12-bus systems with an embedded LCC-HVDC link. Simulation results confirm that the proposed dynamic phasor-based model retains EMT-grade accuracy even at large simulations time steps. Significant acceleration ratios reaching up to an order of magnitude are observed in the simulations using the proposed model compared with conventional EMT models. A real-time EMT variant of the model is then implemented in RTDS real-time simulator. The performance of the dynamic phasor-based model is investigated against existing real-time LCC models with large and small time steps in a hardware-in-loop simulation scenario. The results confirm that the proposed dynamic phasor model retains the same level of accuracy as existing small time-step real-time models while using significantly larger time-steps, thus relieving the burden of real-time computations.

Book Synopsis Efficient Modeling of Modular Multilevel HVDC Converters (MMC) on Electromagnetic Transient Simulation Programs by : Udana Gnanarathna
Download or read book Efficient Modeling of Modular Multilevel HVDC Converters (MMC) on Electromagnetic Transient Simulation Programs written by Udana Gnanarathna and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent introduction of a new converter topology, the modular multilevel converter (MMC) is a major step forward in voltage sourced converter (VSC) technology for high voltage, high power applications. To obtain a multilevel ac output waveform, a large number of semiconductor switches has to be used in the converter. The number of switches in the MMC for HVDC transmission is typically two orders of magnitudes larger than that in a two or three level VSC used in earlier generation. This large device count creates a computational challenge for electromagnetic transients (EMT) simulation programs, as it significantly increases the simulation time. The purpose of this research is to investigate whether the simulation can be speeded up. This research develops an efficient, time-varying Thévenin's equivalent model for the MMC converter based on partitioning the system's admittance matrix. EMT simulation results show that the proposed equivalent model can drastically reduce the computational time without loss of accuracy. The use of the proposed equivalent method is demonstrated by simulating a point to point MMC based HVDC transmission system successfully with more than 100 levels. This approach enables what was hitherto not practical; the modeling of large MMC based HVDC systems on personal computers. With the assumption of ideal switch operation and using an equivalent average capacitor value based approach, an average valued model of MMC is also proposed in this thesis. The average model can be accurately used in most of the system level studies. The control algorithms and other modeling aspects of MMC applications are also presented in this thesis. One of the advantages of multilevel converters is the low operating losses as the smaller switching frequency of each individual power electronics switch and the low voltage step change during each switching. Using a recently developed, time domain simulation approach, the operating losses of the MMC converter are estimated in this thesis. When comparing the MMC operating losses against the losses of two-level VSC, the power loss for the two-level VSC is found to be significantly higher than the power loss of the MMC.
