Abstract: With the continuous increase in the penetration rate of new energy integration and the rapid development of large-capacity cross-regional HVDC transmission, the construction of the new power system is accelerating. During the transition period of the power system, the security and stability issues of the large power grid have become increasingly prominent. The fault ride-through capability of new energy stations will directly affect grid security and stability, and even cause large-scale regional grid disconnection and paralysis.Based on the grid-related test projects for new energy undertaken by Fujian Zhongshisuo Electric Power Testing & Commission Co., Ltd, this paper systematically elaborates on the technical routes, implementation key points and precautions of two typical on-site fault ride-through capability testing schemes: "based on primary power grid simulation device" and "based on secondary high/low voltage ride-through analog signal source". It aims to provide referable practical references for the fault ride-through capability verification of similar projects in the industry, help promote the safe and stable development of new energy in China, and accelerate the construction of the new power system.
