UAD215A104 3BHE026284R0104 UA D215 A104 CSI Converter Signal Interface for UNL14300.The main features of the static self-shunt excitation system are: the wiring and equipment of the excitation system are relatively simple, there is no rotating part, the maintenance cost is low, the reliability is high, no coaxial exciter is required, the length of the main shaft can be shortened, the capital investment can be reduced, and the power generation can be improved at the same time. The stability of the machine shaft system; directly using the thyristor to control the rotor voltage can obtain a fast response speed of the excitation voltage; the energy is obtained from the generator end, and the unit overvoltage is lower than that of the coaxial exciter system when the unit is shedding load; the configuration of PSs can Improve system stability. Although the self-shunt excitation system has these characteristics compared with the three-machine excitation system or the two-machine excitation system, the organic terminal voltage drop is lower when the unit of the self-shunt excitation system is close to the three-phase short circuit, which may cause the possibility of generator loss of excitation. However, due to The large-scale unit adopts unit wiring, and the excitation system has a fast strong excitation function and is equipped with fast protection, which can effectively cut off the fault line ≈. Because of the above characteristics, more and more self-shunt excitation methods are used in domestic and foreign units.
