The Concept of Computing on Chip (CoC) for Electric Power System Application

This paperproposes an inzastructure in which analogdigital mixed VLSI circuit is used to perform transient stability analysis in electric power system. Through proper conJiguration a VLSI circuit can be used to simulate the dynamics in power system in a real-time or even super real-time manner. With currently available VLSI circuit technology large and complex SOC (system-on-chip) can be fabricated on a single chip. With the powefil digital processing capability, a computing-on-chip (CoC) can provide powerful programmability to perform high-speed analog simulation of power system with variable topologies, parameters and operation conditions. In this paper, the system structure and the VLSI implementation ofpow er system stability model is proposed. And the PSpice simulation results is presented, and the results are compared with that of typical digital power system simulation program. It is verified that power system CoC can perform real-time or super real-time stability analysis with acceptable accuracy; hence it is a proposing technology.
