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.

隨著光伏發(fā)電系統(tǒng)快速發(fā)展,以及電動汽車充電樁的普及,傳統(tǒng)的剩余電流保護器無法滿足實際需求。介紹了一款B型剩余電流保護器,采用磁調(diào)制剩余電流互感器和零序電流互感器采集剩余電流。根據(jù)GB/T 22794—2017標準要求,可識別1 kHz及以下的正弦交流、帶和不帶直流分量的脈動直流、平滑直流等剩余電流信號。經(jīng)信號調(diào)理電路將電壓信號送到單片機進行采集和判斷。通過試驗測試,該樣機在測試精度和速度上均符合國家標準的相關(guān)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.

直流電動機具有運動效率高和調(diào)速性能好等諸多優(yōu)點,但傳統(tǒng)的直流電動機均采用電刷,以機械方法進行換向,因而存在致命弱點,再加上制造成本高及維修困難等缺點,從而限制了它的應(yīng)用范圍.近年來隨著永磁材料、現(xiàn)代電力電子技術(shù)、計算機技術(shù)和現(xiàn)代控制理論的迅猛發(fā)展而成熟起來的永磁無刷直流電動機(Brushless Direct Current Motor-BIDCM)具有體積小、重量輕、效率高、噪音低且可靠性高的特點,因而得到了廣泛的應(yīng)用.該文研究的對象是由兩套三相無刷直流電動機組成的六相無刷直流電動機,每套繞組三相對稱,兩套繞組對應(yīng)相之間相差30°電角度.重點研究六相無刷直流電機的轉(zhuǎn)矩特性和系統(tǒng)的可靠性.在分析無刷直流電動機電磁轉(zhuǎn)矩產(chǎn)生原理的基礎(chǔ)上,闡述了三相無刷直流電動機轉(zhuǎn)矩脈動的原因,在此基礎(chǔ)上提出六相無刷直流電動機.分析結(jié)果表明,六相無刷直流電動機的轉(zhuǎn)矩特性優(yōu)于三相無刷直流電機,并且系統(tǒng)的可靠性也較高.該文對無刷直流電動機的工作原理進行了詳盡的分析,建立了三相和六相無刷直流電動機的數(shù)學(xué)模型.并利用MATLAB/SIMULINK軟件建立了三相和六相無刷直流電動機的系統(tǒng)仿真模型.該系統(tǒng)仿真模型采用雙閉環(huán)控制,內(nèi)環(huán)為電流環(huán)(采用滯環(huán)調(diào)節(jié)),外環(huán)為速度環(huán)(采用PI調(diào)節(jié)).對所得的仿真結(jié)果進行分析,表明與理論分析相吻合,證明了六相無刷直流電動機仿真模型的正確性.對兩套繞組可能出現(xiàn)的故障進行仿真分析,結(jié)果表明六相無刷直流電動機具有較強的容錯能力.由此得出結(jié)論,該文提出的六相無刷直流電動機方案是可行的.由于繞組在電機的結(jié)構(gòu)中占有相當重要的位置,該文利用槽號相位表,設(shè)計了三相和六相無刷直流電動機的繞組.對槽號的分配,線圈的連接作了詳細地說明.該文還對三相和六相無刷直流電動機定子繞組的磁勢進行了諧波分析,分析結(jié)果表明了六相無刷直流電動機定子繞組的磁勢高次諧波含量要少于三相無刷直流電動機.
