Linear equation solver of real-time simulators for active distribution networks (ADNs) requires significant computation power. Field programmable gate array (FPGA) has many merits such as highly parallel hardware structure and programmable characteristics, which shows great potential for the real-time solving of linear equations. Considering the sparsity of the linear equation, a parallel solver is designed in this paper based on block triangular form (BTF) matrix block algorithm. The design of off-line processing on host PC and online calculation on FPGA are proposed in detail. Simulation results are compared with PSCAD/EMTDC to validate the correctness and effectiveness of the parallel solver design.
