A circuit topology of the inverter with duty cycle extended active clamp forward style high frequency pulse dc link is adopted by each independent inverter. each inverter is cascaded by a circuit with duty cycle extended active clamp forward style high frequency pulse dc link and a dc / ac inverting bridge. the control strategy of voltage mode pwm forwardback is adopted by the former, and the control strategy of three - state discrete pulse modulation ( dpm ) hystersis current is adopted by the later
每個獨立的航空靜止變流器採用占空比擴展有源箝位正激式高頻脈沖直流環節電路拓撲,由占空比擴展有源箝位正激式高頻脈沖直流環節電路與dc ac逆變橋級聯而成,前級採用電壓型pwm前饋控制技術,后級採用三態dpm電流滯環控制技術。It is a new - style method of the drive control fed by static transducer in the control of the microcomputer, which makes the stator flux movement discrete. and position and speed outputs can be achieved on the motor axes
它是在微機的控制下由靜止變頻器供電,使同步電動機定子磁動勢離散運動,在電動機軸上得到位置和速度輸出的一種新型傳動控制方式。As the most effective means to increase the economics and reliability of power station, pumped storage power station with static frequency converter ( sfc ) for start - up is widely used in developed country. recently china also implements several pumped storage power station projects
抽水蓄能電站利用靜止變頻啟動( sfc )方式啟動,這種方式在啟動時產生諧波,對sfc裝置及同電壓級別的其它用戶產生影響,也會通過降壓變壓器向高壓傳遞,對高壓側的用戶產生影響。The shahe pumped - storage power station with two 50mw reversible units has been in good conditions on general since it was put into operation, but there still were some defects, such as the failure of unit ' s contemporaneous device, the insufficient cooling water discharge and pressure, and the failure of static frequency converter and excitation overcurrent
摘要沙河抽水蓄能電站兩臺50mw可逆式機組自投運以來,總體情況良好,但是也出現了一些缺陷,如機組同期裝置故障,機組冷卻水流量或壓力不足,靜止變頻器故障,勵磁過電流故障等。As for the dynamic performance, the linear variable differential transformer ( lvdt ) displacement sensor using signal conditioner ad598 is not so good, so the differential rectifier is designed as the measuring circuit of the sensor so as to increase its cross - over frequency. also, the static test and dynamic test is made for the sensor along with the lvdt
由於使用線性差動變壓器信號處理晶元ad598為測量電路的差動變壓器式傳感器的動態性能不夠理想,本文設計製作了差動整流電路作為差動變壓器式傳感器的測量電路以提高傳感器的截止頻率,並對差動變壓器式傳感器進行靜態和動態標定。分享友人
