The ABB UNITROL 6000 is the latest - generation indirect and static excitation system, based on the AC800PEC high - performance processor platform, which can meet the needs of various types of synchronous generators and motors. It has a wide range of applications in hydropower plants, pumped - storage power plants, thermal power plants, gas - fired power plants, nuclear power plants, etc. Here is a detailed introduction:
Fast-response Controller: It is equipped with a 600MHz 64 - bit floating - point operation processor, which enables rapid and accurate adjustment of the excitation current, ensuring the stability of the generator's output voltage and power factor.
Redundant Design: It has an independent backup manual channel and internal fully redundant fiber - optic communication, which improves the reliability of the system. In the event of a failure in the main channel, the backup channel can be quickly switched to ensure the normal operation of the excitation system.
Intelligent Current - sharing Technology: The intelligent current - sharing technology can achieve a current - sharing coefficient of over 0.95, effectively prolonging the service life of thyristors and improving the overall efficiency and reliability of the excitation system.
Multiple Power Redundancy: It adopts a multiple - power - supply redundancy design, which makes the system more secure and reliable. Even if one power supply fails, the system can still operate normally through other redundant power supplies.
Compliance with IEEE Standards: It complies with the IEEE 421.5 std PSS 4B model, with a frequency range of 0.01 - 12 Hz, and has good compatibility and adaptability with the power grid.
Product Classification
According to different application fields, it is divided into UNITROL 6800 and UNITROL 6080.
UNITROL 6800: It is mainly used in medium - and large - scale static excitation systems, with an excitation current range of 40 A - 10,000 A. It has more complex functions and is suitable for applications with high - power and high - performance requirements, such as large - scale thermal power plants, hydropower plants, and nuclear power plants.
UNITROL 6080: It is mainly used in three - machine excitation and small - generator excitation systems. It has relatively simple functions and is suitable for some small - and medium - sized power generation equipment.
Composition of the Static Excitation System.
The UNITROL 6800 static excitation system mainly consists of components such as AVR regulation and control electronics, excitation transformers, rectifiers, field - discharge DC switches, and start - up excitation devices. Among them, the core of UNITROL 6800 is the AC800PEC, a powerful ABB power - electronics controller with a 600MHz PowerPC CPU from IBM Motorola and 64 - bit IEEE floating - point calculation capabilities. The software of the controller is developed using MATLAB SIMULINK RTW graphical software, which has strong configurability and expandability.
