Hani Energy Company has nearly two decades of experience in development of various types of electronic cards, excitation system components, and cards.  We serve complete excitation control and protection systems for generators. The design and implementation of all power electronic parts and control parts of the system and its implementation as a DCS system are parts of our technical capabilities in this field.

The most important features of this system include the followings:

• Configuration of Siemens hardware and software-based controls, based on PCS7 300 and 400 class.
• High processing speed of control loops (less than 2 milliseconds).
• Ability to implement the system through hot redundancy in the control, power and cooling systems.
• Reduction of generator losses by placing its working point at the nominal working point which results in better generator efficiency.
• Ability to communicate with the proxy bus network and industrial Ethernet network.
• The ability to change the power of the excitation system from the dynamic to the static mode and the removal of the middle power generators.
• Full control over the generator by various control modes.
• Voltage control in automatic mode or AVR (automatic voltage regulator).
• FCR (Field Current Regulator) flow control.
• Reactive power control and generator power factor in PF (power factor).
• Transmission without mutants between control modes.
• Reactive flow regulator and the ability to determine the line drupe or reactive power drill.
• Soft power generator startup voltage to prevent sudden spin on triggering.
• Contains UEL (under excitation limiter), OEL (over excitation limiter) limiting stator current limiter (SCL) and limiting volts per Hz (V/Hz).
• Display of the generator’s work point in the generator’s power generation curve on the HMI.
• Design of the power sector in two ways to increase the speed of the De-excitation.
• Monitoring the position of rotating diodes in the system of dynamic stimulation and the state of the thyristors in the static excitation system.

The use of this system will reduce the cost of repairing and maintenance and long-term after-sales service.
