6 FAQs about [Base station wind power supply output voltage is low]

Do wind turbines support grid voltage during voltage deviations?

In a power system with a high penetration of wind power generation, it is required that the wind turbines support the grid voltage during voltage deviations to ensure the system's security. After a voltage drop, the system's P – U curve is shown in Figure 2.

Why do wind power and photovoltaics lack voltage support capability?

Wind power and photovoltaics in new energy power systems lack voltage support capability. As the proportion of synchronous generators (SG) decreases, the system's short-circuit capacity also decreases, leading to insufficient short-circuit ratio (SCR).

Why are wind turbines unable to provide short-circuit capacity?

The output power of wind turbines is mainly dependent on wind velocity, resulting in its decoupling from the power system. Therefore, under the current power control methods, wind turbines are unable to provide short-circuit capacity for the power system.

Why do wind turbines have a low short-circuit ratio?

As the proportion of synchronous generators (SG) decreases, the system's short-circuit capacity also decreases, leading to insufficient short-circuit ratio (SCR). The output power of wind turbines is mainly dependent on wind velocity, resulting in its decoupling from the power system.

How to ensure the voltage stability of a wind turbine?

To ensure the system's voltage stability, there are certain requirements for the short-circuit capacity, STP at the grid connection point in the fault test experiments. According to industry standards , its value should be greater than three times the rated capacity, SWTN of the wind turbine.

Can new energy sources improve the voltage stability of grid-forming wind power systems?

The aforementioned research findings are useful for enhancing the voltage stability of power grids with new energy sources, but the transient voltage response of grid-forming wind power systems and parameter ranges lack a theoretical design basis.
