The model of fujian power grid and models of generators , excitation systems , governor systems and loads are established , the tested excitation system models of large hydro and thermal units , the model of wind turbine are established as well in this paper with pss / e , a new software imported from pti of u . s . a . recently . some key points are proposed on data convertion from psasp and bpa to pss / e . the transient and dynamic characteristics between separate excitation system and transformer - fed excitation ( self excitation ) system are compared with pss / e

The mutual excitation between the local stimuli satisfying the rules of curve distribution ( position and orientation continuity ) called curve self - excitation is a useful method to discover and enhance curves and to inhibit noise . the present approaches used parallel connection structure division which did not acquire satifactory effect . this paper presents the idea of random time division and dynamic self - excitation , for different curves performing random time - division searches , time coincidence filtering , and self excitation accumulation . the principle is given
