采用多單元同步控制系統(tǒng)，考慮到煤礦的現(xiàn)場(chǎng)情況和控制距離, 在設(shè)備機(jī)頭設(shè)有本地/遙控轉(zhuǎn)換開關(guān)，既可實(shí)現(xiàn)本地控制, 也可遠(yuǎn)程遙控。3臺(tái)變頻器之間通過開放的RS-485串行通訊網(wǎng)絡(luò)進(jìn)行實(shí)時(shí)通信，實(shí)現(xiàn)數(shù)據(jù)交換。在運(yùn)行中，可以在控制室通過工控機(jī)對(duì)3臺(tái)高壓變頻器同時(shí)給定同步速度，實(shí)現(xiàn)良好的同步關(guān)系。
高壓變頻器系統(tǒng)圖如圖３所示。
運(yùn)行中的高壓變頻器如圖4所示。
5.VT710高壓變頻器特性
（1）滿載時(shí)，包括移相變壓器在內(nèi)的變頻調(diào)速系統(tǒng)效率≥97%；
（2）功率因數(shù)≥95%；
（3）滿足中國(guó)諧波相關(guān)標(biāo)準(zhǔn)；

（5）近似全數(shù)字PWM脈寬調(diào)制技術(shù)；
（6）全功率范圍段的MCU控制；
（7）PWM輸出電壓波形控制在VDC內(nèi)；
（8）直接矢量閉環(huán)控制模式，控制精度萬分之一；
（9）在閉環(huán)矢量控制模式下，VT710的控制范圍是1:100，即以50Hz為基頻，其控制范圍可到0.5Hz。在開環(huán)情況下，VT710的控制范圍也
可達(dá)到1:10，也就是5Hz；
（10）電流跟蹤和磁通補(bǔ)償功能；

6.VT710變頻調(diào)速系統(tǒng)與交流繞線式電機(jī)串電阻調(diào)速系統(tǒng)的比較
6.1 VT710與電機(jī)串電阻調(diào)速相比，有以下突出特點(diǎn)：
(1)起動(dòng)性能優(yōu)越
變頻器采用速度閉環(huán)控制，調(diào)速精度高，啟動(dòng)轉(zhuǎn)矩可以做到等于最大輸出轉(zhuǎn)矩；即使在零速也可以達(dá)到最大轉(zhuǎn)矩。串電阻調(diào)速起動(dòng)過程和調(diào)速換擋過程中電流沖擊大。
(2)系統(tǒng)效率高
變頻器輸出直接和電機(jī)相連接，效率高；繞線式電機(jī)轉(zhuǎn)子串電阻調(diào)速，電阻上消耗大量的轉(zhuǎn)差功率,效率極低。
(3)負(fù)載特性良好
變頻器負(fù)載可以在很大的范圍來調(diào)節(jié)；繞線式電機(jī)轉(zhuǎn)子串電阻調(diào)速范圍有限。
(4)維護(hù)成本低
變頻器的運(yùn)行成本和維護(hù)成本卻遠(yuǎn)遠(yuǎn)比串電阻調(diào)速低。串電阻調(diào)速的日常維護(hù)比變頻器工作量大，維護(hù)成本高。
6.2變頻器系統(tǒng)和繞線式電機(jī)轉(zhuǎn)子串電阻系統(tǒng)綜合比較
變頻器系統(tǒng)和繞線式電機(jī)轉(zhuǎn)子串電阻系統(tǒng)綜合比較如附表所示。
