采用并機(jī)系統(tǒng)，對(duì)于單機(jī)供電有以下優(yōu)點(diǎn)：

　　可以提高供電質(zhì)量和容量，提高系統(tǒng)可靠性，增大直接啟動(dòng)異步電動(dòng)機(jī)能力，系統(tǒng)運(yùn)行靈活、負(fù)載分配合理、簡(jiǎn)化供電系統(tǒng)接線，使機(jī)組運(yùn)行在經(jīng)濟(jì)負(fù)荷狀態(tài)，降低運(yùn)行費(fèi)用和維護(hù)保養(yǎng)費(fèi)用。

　　機(jī)組并機(jī)是指當(dāng)多臺(tái)發(fā)電機(jī)組運(yùn)行時(shí)，將每臺(tái)發(fā)電機(jī)組提供的電源連接匯合成單一電源給負(fù)載的過(guò)程。每臺(tái)機(jī)組必須滿足以下同相序、同電壓、同頻率和同相位四個(gè)條件才能安全無(wú)沖擊的并入整個(gè)系統(tǒng)。

　　   將多臺(tái)發(fā)電機(jī)組并機(jī)時(shí)注意的重要問(wèn)題之一是適當(dāng)?shù)姆峙湄?fù)載。負(fù)載由兩個(gè)部分組成：有功功率（千瓦）和無(wú)功功率（千伏安），有功功率的分配是通過(guò)柴油機(jī)調(diào)速系統(tǒng)提供，無(wú)功功率由發(fā)電機(jī)的自動(dòng)調(diào)壓器來(lái)分配，考慮到實(shí)際設(shè)備調(diào)整范圍，對(duì)兩臺(tái)并機(jī)機(jī)組間的容量差距不應(yīng)超過(guò)2倍以上，即大容量機(jī)組功率不應(yīng)超過(guò)2倍以上小容量機(jī)組功率。

　　   我司提供國(guó)際知名品牌（科邁、深海、凱訊）等全自動(dòng)并機(jī)控制系統(tǒng)，能夠保證機(jī)組并機(jī)的穩(wěn)定性及安全性；降低機(jī)組無(wú)功消耗；為客戶提供安全可靠穩(wěn)定的應(yīng)急電源。

　　 Between the best running status of diesel generator set with 70% to 85% in the unit load.   If the generating units of long-term continuous operation in the load range, not only a serious waste of energy, but also waste generator internal combustion increases, need maintenance and maintenance of the unit more frequently.   When the plant load and load changes in the larger, use many units separate power supply, load some unit is very small, some unit load quantity is very large, in order to start the motor will increase the capacity of generating units but make the units in the light load state, or unit load can not supply appears to failure.   There is a large energy wasting, difficult management, maintenance for many times, the frequency is high, cannot make full use of the existing resources.

By combining system, has the following advantages for single power supply:

Can improve the quality and capacity of the power supply, improves the reliability of the system, increase the ability of asynchronous motor direct starting, flexible operation, reasonable distribution system load, a simplified power system wiring, make the operation of the unit in the economic load condition, reduce operating costs and maintenance costs.

Units and machine is when running more generating units, the power supply of each generating unit connected merged into a single power supply to the load process.   Each unit must meet the following the same phase sequence, the same into the system voltage, frequency and the same phase with the four conditions can be safe without impact.

One of the important problems that attention will be more generating units and machine is the appropriate distribution of load.   The load is composed of two parts: active power (kw) and reactive power (Qian Fuan), distribution of active power is provided by a diesel engine speed regulation system, the reactive power by automatically adjustable generator voltage regulator to adjust the scope of distribution, taking into account the actual equipment, on two stations and machine group capacity gap between should be more than 2 times above, that the power of large capacity units should not exceed more than 2 times the small capacity power generating units.

Our company provide the international famous brand (Comay, deep sea, Kai) and other automatic machine control system, can guarantee the stability and safety of the unit and machine; reduce unit reactive power consumption; to provide emergency power supply safety and stable and reliable for the customer.
