Introduction of excitation system The excitation system is the power system and its ancillary equipment supplied to excitation current for synchronous generator. Excitation Systems includes excitation power and excitation device. The main body of excitation power is exciter or excitation transformer. The excitation device is an electrical control device that controls and adjusts excitation current besides excitation power in excitation systems of synchronous generator. According to different specification, type and operating requirement, it consists of regulating panel, control panel, de-excitation screen and rectifier separately. Excitation system is the important part of generator and is a must-have equipment for power stations. It also has significant influence and effect on the safe and stable operation of the power system and the generator itself. The main function of the excitation system 1. Maintain voltage for a given value of machine side according to the generator load changes to adjust the excitation current corresponding. 2. Control reactive power allocation between parallel operation of the generator. 3. Improve static stability of the generator parallel operation. 4. Improve transient stability of the generator parallel operation. 5. Deexcitation to reduce loss fault when internal generator failure. 6. According to operational requirements to limit the maximum excitation and the minimum excitation of generator. Classification of the excitation As per the excitation mode of DC generator, it can be divided into separate excitation, shunt excitation, cascade excitation, and compound excitation, etc. According to the way of rectifying: 1. Rotating type excitation Rotating type excitation includes DC & AC and brushless excitation. 2. Static type excitation Static type excitation consists of potential source static exciter and composite power static exciter. Company Introduction Found in 1958, our factory in hydropower products has continuously been one of the national strategic turbine manufacturers in China since year 1995. It has now 246,000 square meters ground area and 68,000 square meters office building area. With over 500 workers and over 200 technicians and engineers, ADDNEW's invested factory is certificated by ISO9000-2000 and CE. From the start of 2005 to the end of 2012, ADDNEW and our factory in Hunan, China have designed, manufactured and installed successfully over 170 small Hydroelectric Power Stations in Albania, Chili, Congo, India, Lithuania, Kazakhstan, Vietnam, Zambia and other overseas markets. The equipments adopted for those hydropower stations are unit-capacity from 800KW to 100MW and the total power generating capacities of each station ranging from 1600KW-200MW. All the completed stations are now maintaining their peak performance after their installations.
