This paper examines the use of the symmetrical components theory for the representation of unbalanced conditions, when using the concept of analog emulation for highspeed power system analysis. This concept has been proven and validated through the realization of a mixed-signal hardware platform dedicated to power system studies. Computations related to the grid are handled by analog electronics,...
Coherency group identification is an integral constituent part of the wider field of reduction techniques in power systems. It consists of separating the machines in the system into groups that feature similar behavior. This paper presents a coherency identification algorithm for dynamic studies. The algorithm combines both modal and time domain techniques in an effort to combine the merits of both...
This paper focuses on a new pipelined processing unit architecture dedicated to mixed-signal power system emulation. Prior research in this field has proven that analog emulation overcomes the speed limits of numerical simulators with reliable accuracy. Then, a new concept based on field programmable power network system (FPPNS) has been developed in order to gain in term of flexibility. It is based...
This paper further examines the use of mixed-signal circuits for power system emulation. It has already been proven that analog emulation overcomes the speed limits of numerical simulators by means of a simple fixed-topology prototype. In order to enhance the modularity and the size of the emulated power system a dedicated platform based on a field programmable power network system (FPPNS) has been...
This paper highlights the increasing need for faster than real-time simulators of the electric power system and shows that microelectronic emulation is a very promising solution to overcoming speed problems of current numerical simulators. Research is focused on two different emulation approaches. Both of them are detailed in this paper and their electronic implementation is shown. Furthermore, the...
This paper introduces a microelectronic emulation approach for high-speed power system computation. First, the problems of existing power system simulators are detailed. This shows that microelectronic emulation is a possible solution for the speed problems of existing simulators, using emulation of the power grid to build an instantaneous connection between multiple differential equation solving...
