摘要
Since the digitization and intelligentization of substation technically supports the substation-wide information sharing, a digital integrated protection and control system is thus developed, which consists of three kernels: IT (Intelligent Terminal) at equipment layer, MU (Merging Unit), and MPCU (Multifunctional Protection and Control Unit) at system layer. Their hardware structure and software design scheme are given. Based on IEC61850 standard, the developed system adopts two-step phasor calculation and two-step protection startup criterion to improve the rapidity and reliability of relay protection. Test results show that, it responses to fault rapidly and reliably, and its capability of centralized communication and calculation satisfies the requirements of protective trip.
