Explanation of professional terms and practical application cases
Voltage source converter (VSC): An AC/DC converter that uses DC capacitors to provide smooth DC voltage. It is widely used in flexible DC transmission systems. Its core function is to achieve precise control of power electronic devices to ensure stable operation of the power grid.
Modular Multilevel Converter (MMC): It is composed of multiple standard components, and each submodule contains an IGBT-diode pair and auxiliary equipment. In practical applications, MMC achieves efficient energy transmission through dynamic voltage regulation and is suitable for high voltage and high current applications.
Standard Formulation Background and Technological Evolution
With the rapid development of flexible DC transmission technology, the performance and reliability of the converter valve as a core device directly affect the operating efficiency of the entire system. The formulation of GB/T 37010-2018 fully considers the technological development trends at home and abroad, and optimizes and improves the existing standards based on actual engineering experience.
