An algorithm design of sequential component in the aircraft electrical system

An algorithm for the calculation of the sequential parameters in the aircraft electrical system is designed in this paper. The original calculation model of the sequential component calculation is given as a complex formula which is inconvenient for the general digital programmable computation. The geometrical algorithm is presented in this paper in which the voltage vectors rotate and project to the coordinate axis to simplify the calculation. The projections on x and y coordinates may add up in algebra way, and only one projection is left on each axis. Then synthesize the two components to obtain the required sequential voltage vector. This algorithm may be used in the program design by ordinary programming languages in the fault diagnostics and protection to the electrical system. The asymmetry calculation by hand is also made possible.
