The Open Radar Data Acquisition (ORDA) subsystem replaces the current WSR-88D Radar Data Acquisition subsystem with improved receiver and signal processing hardware and with improved user interface, signal processing and diagnostics software. This paper will discuss the input data from the digital receiver, the ORDA signal processing, and the data output from the ORDA hardware. Specifications of the ORDA digital receiver will be presented. The paper outlines the critical radar signal processing flow and provides analysis of new spectrum width computations and clutter filtering schemes used in the ORDA system. Where appropriate, ORDA performance enhancements, data quality improvements and reliability and maintenance improvements will be highlighted.

随着光伏发电系统快速发展,以及电动汽车充电桩的普及,传统的剩余电流保护器无法满足实际需求。介绍了一款B型剩余电流保护器,采用磁调制剩余电流互感器和零序电流互感器采集剩余电流。根据GB/T 22794—2017标准要求,可识别1 kHz及以下的正弦交流、带和不带直流分量的脉动直流、平滑直流等剩余电流信号。经信号调理电路将电压信号送到单片机进行采集和判断。通过试验测试,该样机在测试精度和速度上均符合国家标准的相关要求。The rapid development of photovoltaic power generation systems and the popularity of electric vehicle charging piles make the traditional residual current protective devices unable to meet the actual demand.This paper proposed a type B residual current protective device,which uses the magnetically modulated residual current transformer and the zero sequence current transformer to acquire the residual current.According to the requirements of GB/T 22794—2017,the type B residual current protective device can detect sinusoidal AC residual current of 1kHz and below 1kHz,pulsating DC residual current with and without DC component,smooth DC residual current and so on.The signal processing circuit sends the voltage signal to the MCU for acquisition and judgment.Through experimental tests,the device meets the relevant requirements of national standards in terms of test accuracy and speed.

直流电动机具有运动效率高和调速性能好等诸多优点,但传统的直流电动机均采用电刷,以机械方法进行换向,因而存在致命弱点,再加上制造成本高及维修困难等缺点,从而限制了它的应用范围.近年来随着永磁材料、现代电力电子技术、计算机技术和现代控制理论的迅猛发展而成熟起来的永磁无刷直流电动机(Brushless Direct Current Motor-BIDCM)具有体积小、重量轻、效率高、噪音低且可靠性高的特点,因而得到了广泛的应用.该文研究的对象是由两套三相无刷直流电动机组成的六相无刷直流电动机,每套绕组三相对称,两套绕组对应相之间相差30°电角度.重点研究六相无刷直流电机的转矩特性和系统的可靠性.在分析无刷直流电动机电磁转矩产生原理的基础上,阐述了三相无刷直流电动机转矩脉动的原因,在此基础上提出六相无刷直流电动机.分析结果表明,六相无刷直流电动机的转矩特性优于三相无刷直流电机,并且系统的可靠性也较高.该文对无刷直流电动机的工作原理进行了详尽的分析,建立了三相和六相无刷直流电动机的数学模型.并利用MATLAB/SIMULINK软件建立了三相和六相无刷直流电动机的系统仿真模型.该系统仿真模型采用双闭环控制,内环为电流环(采用滞环调节),外环为速度环(采用PI调节).对所得的仿真结果进行分析,表明与理论分析相吻合,证明了六相无刷直流电动机仿真模型的正确性.对两套绕组可能出现的故障进行仿真分析,结果表明六相无刷直流电动机具有较强的容错能力.由此得出结论,该文提出的六相无刷直流电动机方案是可行的.由于绕组在电机的结构中占有相当重要的位置,该文利用槽号相位表,设计了三相和六相无刷直流电动机的绕组.对槽号的分配,线圈的连接作了详细地说明.该文还对三相和六相无刷直流电动机定子绕组的磁势进行了谐波分析,分析结果表明了六相无刷直流电动机定子绕组的磁势高次谐波含量要少于三相无刷直流电动机.
