Abstract


Due to the unbalanced nature of the distribution of China's energy and economic development , making the West to East and national network is imperative . The high-voltage direct current transmission (HVDC) because of its advantage of grid interconnection and long distance transmission , and will play an important role in the West to East and national network . Rapid controllability of HVDC transmission system stability , low-frequency oscillation damping system , economy to achieve long-range , high-capacity transmission . Papers of the advantages and disadvantages of a high voltage direct current technical performance , and pointed out the the HVDC role in China 's electricity system , application and development Research . Combined with China 's national conditions and transmission needs , the need for special HVDC (UHVDC) analysis indicates that it will constitute the main body of our higher-level grid . Wiring program and control characteristics of Yunnan-Guangdong UHVDC Transmission Project Manifolds introduced , compared with conventional DC power transmission project . Thesis developed HVDC dynamic simulation experiment device goals, focusing on control strategies for HVDC dynamic simulation system , the design of the main circuit and the control and protection system . An outline of the HVDC regulation principle and hierarchical controller design method , a comprehensive regulation scheme , as the prototype HVDC dynamic mode the main circuit , the steady-state and transient operating performance of HVDC based EMTDC simulation study prove the rationality and feasibility of the control program . This paper introduces a dynamic simulation laboratory school the existing HVDC dynamic model experimental system , summarizes the principles and methods of dynamic simulation , on the basis of the existing main circuit , the function of the HVDC system dynamic simulation experiment design , according to the visualization and convenient control requirements , and gives a complete control and protection device implementations .
