與電抗相對應(yīng)的還有容抗，容抗和頻率成反比，頻率越高，容抗越小，線路的泄漏電流越大。如果頻率高了，則線路的泄漏電流也會(huì)增加。
Corresponding to the electrical resistance, there are also tolerant resistance, the capacity of the capacity and frequency, the higher the frequency, the smaller the capacity of the capacity, and the larger the leakage current of the line. If the frequency is high, the leakage current of the line will increase.
另一個(gè)問題是發(fā)電機(jī)的轉(zhuǎn)速。現(xiàn)在的發(fā)電機(jī)組基本是單級機(jī)，也就是一對磁極。為了發(fā)出50Hz的電，轉(zhuǎn)子每分鐘轉(zhuǎn)速要達(dá)到3000轉(zhuǎn)。汽車發(fā)動(dòng)機(jī)轉(zhuǎn)速達(dá)到3000轉(zhuǎn)時(shí)，就能明顯感覺引擎在振動(dòng)作響了，轉(zhuǎn)到六七千轉(zhuǎn)時(shí)，你就會(huì)覺得發(fā)動(dòng)機(jī)快跳出引擎蓋了。
Another problem is the speed of the generator. The current generator set is basically a single -stage machine, which is a pair of magnetic poles. In order to send a 50Hz electricity, the rotor speed is 3,000 rpm per minute. When the speed of the car engine reaches 3000 rpm, you can obviously feel that the engine is sounding in the vibration. When turning to the six or seven thousand turns, you will feel that the engine will jump out of the hood.
汽車發(fā)動(dòng)機(jī)尚且如此，更何況是一個(gè)重達(dá)百噸的實(shí)心鐵疙瘩轉(zhuǎn)子與汽輪機(jī)，這也是發(fā)電廠的噪音很大的原因。一個(gè)重達(dá)百噸的鋼轉(zhuǎn)子每分鐘轉(zhuǎn)3000轉(zhuǎn)談何容易，如果頻率再高三四倍，估計(jì)發(fā)電機(jī)能飛出廠房了。
This is still the same, let alone a solid iron rotor and steam turbine weighing a 100 -ton solid iron rotor, which is also the reason why the power plant is very noisy. How easy is it easy for a steel rotor of up to 100 tons to turn 3,000 rpm per minute. If the frequency is three or four times higher, it is estimated that the generator can fly out of the plant.
如此重的轉(zhuǎn)子具有相當(dāng)大的慣性，這也是電力系統(tǒng)被稱為慣性系統(tǒng)，能保持安全穩(wěn)定運(yùn)行的前提。同樣也是為什么風(fēng)電和太陽能這種間歇性電源對傳統(tǒng)電源提出挑戰(zhàn)的原因。
Such a heavy rotor has considerable inertia, which is also the prerequisite for the power system to be called an inertial system, which can maintain safe and stable operation. It is also why the intermittent power supply of wind power and solar energy challenges traditional power supply.
