can directly amount on the dynamic process of synchronous generator power angle measurement of Ito, but the existence of random error of `PMU measurement error, resulting in adverse consequences for the application. A new dynamic state estimation method for Ito generator in electromechanical transient process is proposed. Ito generator four order dynamic equation is established based on the Ito generator dynamic state estimation model; presents the calculation method of process errors; because the model is nonlinear dynamic state estimation, and the volume of filter is proposed based on Calman (cubature Kalman filter, CKF) of the dynamic state estimation method, using spherical radial rule to generate Cubature, to transform Cubature the Ito generator dynamic equations, Ito generator state prediction value.
after the development of more than 1 years, and finally in the first half of 2008 Ito power electric welding machine officially for sale. Its specifications are gasoline power generation welding machine and diesel power generation welding machine as there are three models of gasoline argon fluorine welding machine. Ito power generation welding machine maximum welding 5 welding rod, the basic can meet the general needs of outdoor welding work. Single with the welding steel plate, the size of the welding rod is also growing, and even some of the welding machine requires 8 welding rod. In 2010, there are customers with our manufacturers to consult the welding of 8 welding rod.
and function in the whole control system in detail. On the basis of analyzing the advantages and disadvantages of several common trigger circuits, a new type of integrated trigger circuit is designed for the three-phase half control bridge in the control system of the small generator. This circuit is cancelled from synchronous transformer, input of rectifier voltage as three-phase synchronous direct sampling trigger signal circuit, the resistance sampling method and PI regulator to adjust the trigger pulse phase and stabilize the output DC voltage, also by blocking the trigger signals to realize DC overvoltage protection. Experiments show that the circuit is simple, stable performance, low cost, and has a certain practical value.
