Generator Static Excitation System – MAPEX-E Class

Application:

used In thermal, hydroelectric and gas power plants to control the operation of the generator (class E) and regulate its voltage and reactive power


Certified ByTrust

Product Introduction:

The rotor of power plant generators should be fed by a DC current that is suitable for the generator’s working conditions. In case of an error in the network, the rotor circuit undergoes many changes and its current and voltage increase greatly. The excitation system has the task of controlling the electrical parameters of the rotor circuit in normal conditions or faults in the network, and if the excitation system operates correctly, maintaining the health of the generator in different working conditions is guaranteed. Since the changes of the electrical parameters of an electrical circuit can be very fast, the excitation system must determine the status of the rotor circuit and the generator at a high speed and ensure the safety of the generator operation with a suitable reaction. The control system consists of a control loop that has protective parts called current and excitation voltage limiters, stator, PSS, etc.
