Problems solved by technology

[0002] The connection of large-scale wind farms to the power grid will have adverse effects on the safe and stable operation of the power system, power quality, and real-time power balance. The centralized start and stop of a large number of wind turbines is not conducive to the stable operation of the power grid. The normal operation of the power plant, the safety and stability of the power system, and the improvement of power quality have an important impact; the large-scale fan off-grid of the wind power system indicates that the reactive power compensation device is not fully suitable for the electrical characteristics of the new energy power generation system and its connection with relay protection.

[0003] The existing TCR-type SVC reactive power compensation device designed to meet the needs of specific project operations cannot simulate the operating characteristics of the fault state, and cannot use the device itself to study the impact of various fault modes on the system, and the operating conditions of the device site are also impossible. Therefore, it is impossible to use field devices to deeply study important issues such as the influence of the dynamic process of TCR reactive power compensation equipment on the characteristics of relay protection in power systems.
