抽頭變壓器 的英文怎麼說
中文拼音 [chōutóubiànyāqì]
抽頭變壓器
英文
subdivided transformer-
If the filament transformer has a center tap, don ' t use it
如果變壓器燈絲繞組有抽頭，請不要使用它。Centre - tapped transformer
中心抽頭變壓器The fourth advantage of this circuit is since the transformer has no high voltage dc on it, the transformer can be replaced with an " autoformer " ( a single tapped winding ) allowing the output autoformer to be further optimized
第四：由於輸出變壓器不需要通直流，變壓器可以使用「自耦」式單一抽頭繞組，從而容許進一步優化輸出自耦。Replacement of high voltage switchboards, transformers and low voltage system of the tunnel power supply system in lion rock tunnel, replacement of field equipment of toll collection system in cross - harbour tunnel and replacement of ventilation control panels, exhaust fans, motors and flexible connectors in aberdeen tunnel

隨后，在基於分解電壓測量量和功率測量量的估計演算法的基礎上，對狀態估計中經常出現的變壓器抽頭位置問題和零阻抗支路潮流估計問題進行了分析和處理；對狀態估計的不良數據檢測與識別方法進行了推導和模擬，並提出了一種混合檢測方法。Through analyzing the mathematical model of two winding transformer, the effect after on - load tap changing on voltage and reactive power balance at each side, effect of shunt capacitor compensation on voltage and reactive power balance in substation the relation between transformer tap adjusting and shunt capacitor switching in practical grid operation were discussed
摘要通過對兩卷變壓器的數學模型進行分析，討論了兩卷變壓器抽頭調整后，變電站各側電壓及無功功率的變化；無功補償對變電站各側電壓及無功功率的影響；實際電網生產運行中，無功補償與變壓器抽頭的配合調整。This algorithm improves confidence in se by estimating parameters and states at the same time. simulation results on test power systems which range in size from 4 to 118 buses, have shown the virtues as follows : getting unbiased estimation without detecting and identifying bad data in measurements ; solving state and parameter estimation for power system with good convergence and excellent robust property ; increasing the numbers of iterations a little bit with the test systems expanded ; estimating many transformer taps simultaneously and remaining the main state estimation ; keeping the estimated relative error within + 0. 1 % and processing efficiently equality constraints and ill condition with polynomial complexity
對ieee ? 4 118節點系統和廣西主網進行的模擬結果表明： l1范數估計具有不良數據拒絕特性，當量測量中存在不良數據時，該演算法在不經檢測和辨識不良數據情況下仍是無偏估計，具有良好收斂性，所需迭代次數隨著問題規模擴大而增長極小；能夠同時估計多個變壓器抽頭，並保持狀態估計主體；在滿足可觀測性條件下，估計的相對誤差保證在0 . 1以內；能夠有效處理等式約束和病態條件，並具有多項式時間性。Transformer tap position changes frequently in power systems. if control center does n ' t receive correct network parameters, se ca n ' t get the real network states
系統中變壓器抽頭位置的變化十分頻繁，若調度中心不能及時得到正確的網路參數，狀態估計的結果將不能真實反映當時的網路狀態。分享友人
