Fault Ride Through capability is the ability of Generating Units to remain connected to the Power System during the faults and disturbances. One can argue that, the power system or grid must also be able to ride through faults and disturbances without collapsing or suffering damage. Is this abilica can name as fault ride through capability of a power system? Is there any other technical aspects linked with this topic?
FRT codes are basically focused on generators and voltage level they are connected to (as they are required to follow the norms based on grid codes) and are country specific.
eg: in Poland generating units must stay connected to the grid when the short circuit is cleared with time: t =120 ms for 220 kV and 400 kV grid, t = 150 ms for 110 kV grid.
Some generators in power system are allowed to disconnect during FRT while other generators which are effected by temporary reduction in voltage still required to remain connected and participate in FRT. So in my opinion FRT is not the capability of power system as a whole, but capability of individual generating unit connected.
Yes, you are correct that the power system or grid must also have the capability to ride through faults and disturbances without collapsing or suffering damage. This ability is often referred to as the Fault Ride Through (FRT) capability of the power system.
FRT is a crucial requirement for both generating units and the power system as a whole to maintain stable and reliable operation during faults and disturbances. The FRT capability of generating units ensures that they remain connected to the power system and continue to provide power during transient events, such as voltage dips or short circuits.
On the other hand, the FRT capability of the power system as a whole ensures that it can withstand and recover from faults and disturbances without causing damage to the system or its components. This includes aspects such as fault detection, isolation, and system protection, as well as the ability to quickly restore power to affected areas.
There are several technical aspects linked with the FRT capability of power systems and generating units. These include:
Overall, the Fault Ride Through capability of generating units and power systems is essential for maintaining a stable and reliable power supply during faults and disturbances. It requires proper control, protection, and system design, and compliance with grid codes and regulations to ensure safe and reliable operation.
Yes, the ability of a power system to remain stable and continue to operate during faults and disturbances is often referred to as its "fault ride through capability". However, there are many technical aspects linked with this topic beyond just the ability of the power system to remain stable during faults.
For example, the design and operation of the power system's protection system play a critical role in ensuring fault ride through capability. The protection system must be able to detect and isolate faults quickly and accurately, while also allowing the healthy parts of the system to continue operating normally. In addition, the power system's voltage control and reactive power capabilities are also important for maintaining stability during faults, as they can help to mitigate voltage drops and other disturbances that may occur.
Furthermore, the ability of generating units to ride through faults and disturbances is also dependent on their own design and capabilities. For example, many modern wind turbines and solar power plants are equipped with advanced power electronics that allow them to ride through faults and maintain grid stability even during severe disturbances.
Overall, fault ride through capability is a complex and multifaceted topic that involves many different technical aspects, from power system protection and control to the design and capabilities of individual generating units.
