【摘要】：隨著我國(guó)經(jīng)濟(jì)快速的發(fā)展，人民生活質(zhì)量的日益改善，，電梯的使用量在逐年增長(zhǎng)，電梯與國(guó)計(jì)民生的聯(lián)系也變得越來(lái)越緊密，電梯安全性能也越來(lái)越受到全社會(huì)的密切關(guān)注。電力電子器件完成功率傳送和電能形式變換的同時(shí)會(huì)產(chǎn)生非正弦波的信號(hào)，通過(guò)電磁輻射或電源線進(jìn)行傳導(dǎo)，會(huì)對(duì)附近電氣設(shè)備產(chǎn)生電磁干擾，會(huì)造成電網(wǎng)電壓波形畸變。還有，現(xiàn)代電梯普遍地應(yīng)用了計(jì)算機(jī)控制技術(shù)和微電子技術(shù)，相對(duì)于傳統(tǒng)繼電器控制系統(tǒng)更容易受到外界電磁環(huán)境的干擾。因此，限制電梯的電氣設(shè)備通過(guò)電磁輻射或電源線的干擾以及提高自身抵御外界電磁干擾的能力已經(jīng)成為電梯產(chǎn)品的一項(xiàng)新要求。 利用濾波器抑制電磁干擾是電梯控制系統(tǒng)抗干擾的最有效的方法之一。本文的主要課題是通過(guò)利用EMI濾波器來(lái)降低電梯控制系統(tǒng)的電磁干擾強(qiáng)度。針對(duì)該問(wèn)題首先提出了采用CM/DM分離方法，利用傳導(dǎo)干擾測(cè)試儀器LISN的工作原理，及電梯控制系統(tǒng)電源側(cè)電磁干擾的特性，將電源側(cè)共模噪聲和差模噪聲進(jìn)行分離。 同時(shí)，針對(duì)源阻抗與負(fù)載阻抗的失配將導(dǎo)致電源側(cè)濾波器插入損耗受影響的問(wèn)題，介紹了利用網(wǎng)絡(luò)分析儀來(lái)測(cè)量電源側(cè)濾波器的端口網(wǎng)絡(luò)的S參數(shù)，以及根據(jù)實(shí)際控制系統(tǒng)源阻抗與負(fù)載阻抗可以計(jì)算得到其在正常工作條件下的插入損耗。解決了電梯控制系統(tǒng)電源側(cè)EMI無(wú)源濾波器源阻抗和負(fù)載阻抗失配問(wèn)題，為此設(shè)計(jì)并驗(yàn)證了電梯控制系統(tǒng)電源側(cè)EMI無(wú)源濾波器和EMI有源濾波器在測(cè)試及仿真條件下的符合情況。 實(shí)驗(yàn)結(jié)果證明本文所設(shè)計(jì)的電梯控制系統(tǒng)電源側(cè)EMI無(wú)源濾波器和EMI有源濾波器分別在正常狀態(tài)下的測(cè)試及仿真結(jié)果滿足電梯電磁兼容標(biāo)準(zhǔn)的相關(guān)規(guī)定。
[Abstract]:With the rapid development of our economy and the improvement of people's quality of life, the use of elevators is increasing year by year, and the relationship between elevators and the national economy and people's livelihood has become more and more close. The safety performance of elevator is paid more and more attention by the whole society. Power electronic devices can produce non-sinusoidal signals by electromagnetic radiation or power lines when power transmission and power form conversion. Electromagnetic interference will occur to nearby electrical equipment, which will cause voltage waveform distortion in the power network. In addition, computer control technology and microelectronics technology are widely used in modern elevators. Compared with the traditional relay control system, it is more vulnerable to the external electromagnetic environment. It has become a new requirement to limit the electrical equipment of elevator by electromagnetic radiation or power line interference and to improve its ability to resist external electromagnetic interference. Using filter to suppress electromagnetic interference is one of the most effective methods for anti-jamming of elevator control system. The main task of this paper is to reduce the intensity of electromagnetic interference of elevator control system by using EMI filter. First of all, the CM/DM separation method is proposed. The common mode noise and differential mode noise on the power side of the elevator control system are separated by using the principle of LISN and the characteristics of electromagnetic interference on the power side of the elevator control system. At the same time, aiming at the problem that the mismatch of source impedance and load impedance will affect the insertion loss of power side filter, this paper introduces the measurement of S parameters of power side filter port network by network analyzer. According to the actual control system source impedance and load impedance, the insertion loss can be calculated under normal working conditions. The mismatch of source impedance and load impedance of EMI passive filter on power side of elevator control system is solved. Question. This paper designs and verifies the conformance of EMI passive filter and EMI active filter on the power side of elevator control system under the conditions of test and simulation. The experimental results show that the test and simulation results of EMI passive filter and EMI active filter on the power side of elevator control system under normal condition meet the requirements of EMC standard. .
