摘要
针对母线保护的高要求构造了利用高性能数字信号处理器(DSP)芯片为CPU的微机式母线保护装置硬件平台。在此高性能平台下提出了对母线保护装置启动、抗区外故障电流互感器饱和及母线运行方式自适应识别的新算法。这样可提高母线保护的速动性、灵敏性、防误动和抗拒动的能力。并在工程应用中验证了新型母线保护装置的有效性。
To meet the high requirement of bus-bar protection,a hardware platform using high performance digital signal processor chip as CPU is developed. Based on the platform, a new algorithm for device operating, resisting current transform saturation and identificating bus-bar operation mode is proposed. Thus,the rapidity,sensitivity,ability against the mal operation and ability of resisting operation failure of bus-bar protection are significantly improved. The characteristic of the hardware and principle of the new scheme are briefly introduced. The new bus bar protection device is proved to be valid in practical projects.
