摘要
本文介绍了基于模块化的三模冗余DSP结构设计的船舶电站自动并车装置,应用动态调整采样间隔的交流采样算法来计算交流电量并推导了最小二乘曲线拟合算法来精确预报同期点。装置在硬件上采用多数表决输出的三模冗余结构和在软件上实现数据的冗余处理,能保证在电网品质恶劣的船舶电站中使用时也具有较高的可靠性。
This paper presents an automatic parallel equiment based on triple modular redundant DSP structure in ship power station, which calculates the electrical parameters using AC sampling method with dynamically adjusting synchronous-sampling-time,, and evolves the least square method to forecast the precise synchronization.To guarantee an excellent performance when used in ship power station with rough electric paremeters, the equipment provides a hardware structure of triple-microprocessor system based on majority rule with a specifically-designed software which processes redundant data to achieve a better result.
