At that time, strong emphasis was placed on development of procedures and preparation of automation systems for protection and restoration of the power system. Those requirements are still applicable today. As part of those plans the following can be done in the NPS:. One example is the failure in Szczecin 8 April In this case, the units in base-load power plants, at least most of them, remain in operation with the grid and loads.
An extreme case of major system failure is blackout in the system and shutdown of units in all thermal power plants. Hydropower plants with sufficient power rating are such sources in power systems.

As shown in Fig. This number is not satisfactory. An increase in the number of hydropower plants which may not maszgn start power units in thermal power plants, but also simultaneously and quickly join the subsystem restoration process supply for consumers should be desired.
Consumption of reactive power by loads would compensate, at least in part, the power generated in excess by high voltage power lines, i. It should mazyn noted that in view of high reactive power generated by power lines, construction of start-up lines composed of lines with rated voltage of kV and kV should be avoided, as far as possible.
Diagram of supply line for auxiliary equipment in unit no. The hydroelectric set consists of [ 7 ]:. In this figure, unit no. The synchronous generator of unit no. Only minor loads supplied from auxiliary busbars of unit no. Diagram of supply circuit for auxiliary equipment in unit no. Status before start-up of motors of auxiliary equipment.
Then, auxiliary equipment in unit no. The sequence of the above-mentioned steps and the overall active power consumption by auxiliary equipment in unit no. The start-up itself is also in the form of idling fans and mills or partial load pumps. Start-up of auxiliary equipment and the overall active power consumed by auxiliary equipment in unit no. The selected parameters characterising the start-up process for auxiliary motors are shown in Tab.
The data and Fig. Selected parameters that characterise start-up of auxiliary motors. The next and last operation carried out during the system experiment is synchronous generator excitation and its synchronization with the grid.
Some basic information about the module
The self-starting capability of hydropower plants should not be underestimated. Energa is one of the four largest power groups in Poland. We supply electricity to more than 2. Bajoreo is a university with imagination and future.
