Hybrid Model of Computer Protection Operation Logic Based on PNPT and Development of Dynamic Logic Diagnosis Software
Zhihui Dai, Zengping Wang · 2009
This paper proposes the concept of 'quasi-hybrid model' and presents a new kind of dynamic relaying logic hybrid model based on programmable time Petri net (PTPN) and visualize software which could meet the need of dynamic display and analysis for the relaying logical relation, playback of fault and relaying program debugging expediently. Logic unit library is created in type of integrated prototype and figure. Figure platform could be supplied by drawing logic diagram with this software. Also, dynamic and visual analytical function of the protective relaying action is put into effect.
