Introduction

Each HVDC project are based on the specific requirements of their access to system design, manufacture and test, including its rated power, the amount of Important parameters constant voltage, performance requirements are in accordance with the specific requirements of the selected access system optimization. HVDC systems AC PLC filter Wave capacitor far as other communications equipment standardization, serialization and standardization. Standardization of equipment is conducive to the design, manufacture, testing, drop Low equipment costs, reduce project cost, promote the development of HVDC. Currently no filtering electrical AC PLC for HVDC transmission system Container and the development of standards, the manufacturers according to their respective technical requirements for the design, manufacture and testing of these products and therefore to develop a unified Standard is necessary. Foreign supplier of such products earlier, but not specifically for the HVDC system with PLC AC filter capacitor and the development of standards. The HVDC transmission system developed by the AC filter capacitor standard PLC should fully reflect the study of HVDC equipment Results. With ultrasound, construction HVDC project exchange field, our in extra and ultra high voltage DC AC field engineering research, design, construction, operation Bank and other aspects have accumulated experience, so we have full power to establish their own intellectual property HVDC systems with AC PLC filter Wave standard capacitor. HVDC System AC PLC Smoothing capacitor
