摘要(Abstract):
针对目前暂态录波指示器录波同步性能差、硬件设计成本较高的问题,提出了一种基于微功率无线的低功耗三相同步录波方案。该方案通过对比相邻两次对时之间的采样位置信息,计算出B相、 C相相对于A相的采样计数偏移,并通过逐步微调B相、 C相的采样间隔来同步于A相采样,最终实现了A, B, C三相同步录波。分析了该方案同步性能的影响因素,从低功耗的角度设计了一种通信机制。该方案已在暂态录波型故障指示器上进行了大批量测试验证,结果表明,该方案具有三相录波同步性高的特点,可满足暂态录波指示器录波同步性能的需求,具有广泛的应用前景。
In view of the shortcomings of transient recorder type fault indicators, such as poor synchronization performance and high hardware design costs, a low power three-phase synchronous recording solution based on the micro-power wireless communication technology is proposed. Through comparison of sampling location information between two synchronizations, the sampling synchronization deviations of phases B and C in contrast to phase A are figured out, and phases B and C are synchronized to phase A by their sampling interval adjustment to achieve three-phase synchronization recording. The paper analyzes influencing factors of the performance of the scheme and formulates a communication mechanism for low power. The scheme has undergone the batch test and verification of the transient recorder type fault indicator. The result shows that the scheme features high synchronization performance and can meet the demand of synchronization performance and owns a wide application prospect.
