燃?xì)獍l(fā)電機(jī)組的應(yīng)用比較廣泛，不同的應(yīng)用場(chǎng)景下發(fā)電機(jī)組運(yùn)行模式也有所區(qū)別。下面就來講講燃?xì)獍l(fā)電機(jī)組的運(yùn)行模式及特點(diǎn)，希望能您好的幫助。

Gas turbine generator sets are widely used, and their operation modes are different in different application scenarios. Now let's talk about the operation mode and characteristics of the gas generator set. I hope you can help me.

1并網(wǎng)運(yùn)行

1 Grid connected operation

并網(wǎng)運(yùn)行定義：分布式能源系統(tǒng)發(fā)電機(jī)組與公共電網(wǎng)在用戶端并列運(yùn)行，并向公共電網(wǎng)輸送電能的方式。

Definition of grid connection operation: the way in which the generator units of the distributed energy system operate in parallel with the public grid at the user end and transmit electric energy to the public grid.

并網(wǎng)運(yùn)行是為常見的運(yùn)行模式，對(duì)于發(fā)電機(jī)組而言也是為簡(jiǎn)單的運(yùn)行模式。在并網(wǎng)運(yùn)行模式下，發(fā)電機(jī)組需要通過電網(wǎng)狀態(tài)監(jiān)測(cè)裝置，實(shí)時(shí)監(jiān)測(cè)電網(wǎng)狀態(tài)。一旦電網(wǎng)發(fā)生故障，例如突然失電，監(jiān)測(cè)裝置迅速給出信號(hào)，發(fā)電機(jī)組控制系統(tǒng)立即斷開出口斷路器，切斷與電網(wǎng)的聯(lián)系。在這種模式下，發(fā)電機(jī)組與電網(wǎng)斷開后即進(jìn)入停機(jī)程序。

Grid connected operation is a common operation mode, and also a simple operation mode for generator sets. Under the grid connected operation mode, the generator unit needs to monitor the grid status in real time through the grid status monitoring device. Once the power grid fails, such as sudden power loss, the monitoring device will quickly send a signal, and the generator set control system will immediately disconnect the outlet circuit breaker and cut off the connection with the power grid. In this mode, the generator set will enter the shutdown procedure after being disconnected from the grid.

2孤島運(yùn)行（孤網(wǎng)運(yùn)行）

2 Island operation (isolated network operation)

孤島運(yùn)行定義：分布式能源系統(tǒng)發(fā)電機(jī)組與公共大電網(wǎng)完全脫開獨(dú)立運(yùn)行的方式。

Definition of isolated island operation: the mode of independent operation of distributed energy system generator units completely separated from the public power grid.

在孤島運(yùn)行模式下，燃?xì)獍l(fā)電機(jī)組沒有電網(wǎng)的支撐，完全由自身提供負(fù)荷所需電能。發(fā)電機(jī)組的帶載性能決定了所能承載的負(fù)荷大小以及波動(dòng)。ISO8528-5規(guī)定了G1-G4四個(gè)類別，分別對(duì)應(yīng)不同的負(fù)荷種類和級(jí)別。發(fā)電機(jī)組廠商根據(jù)ISO8528-5的定義，給出了機(jī)組在相應(yīng)的等級(jí)下大能承受的負(fù)荷情況。

In the island operation mode, the gas generator unit is not supported by the power grid, and the power required by the load is completely provided by itself. The load performance of generator sets determines the load that can be carried and its fluctuation. ISO8528-5 specifies four categories G1-G4, which correspond to different load categories and levels. According to the definition of ISO8528-5, the generator set manufacturer gives the load that the unit can bear under the corresponding level.

并網(wǎng)不上網(wǎng)

Grid connected but not connected

由于各種原因，許多天然氣分布式能源項(xiàng)目無法向電網(wǎng)輸出電力，或者因經(jīng)濟(jì)性不佳而有意不向電網(wǎng)輸出電力，這種即為并網(wǎng)不上網(wǎng)模式。但是發(fā)電機(jī)組仍然與電網(wǎng)連接，當(dāng)發(fā)電機(jī)組功率比負(fù)荷小時(shí)，剩余電能由電網(wǎng)補(bǔ)充。在并網(wǎng)不上網(wǎng)模式下，一般由發(fā)電機(jī)組充當(dāng)主用電源，電網(wǎng)作為備用電源。

For various reasons, many natural gas distributed energy projects are unable to output power to the grid, or intentionally do not output power to the grid due to poor economy. This is the grid connected non grid mode. However, the generator set is still connected to the grid. When the power of the generator set is smaller than the load, the remaining electric energy is supplemented by the grid. In the mode of grid connection without grid connection, the generator set is generally used as the main power supply and the grid is used as the standby power supply.

并網(wǎng)和孤島自動(dòng)切換

Grid connection and island automatic switching

有些情況下，機(jī)組需要在并網(wǎng)和孤島模式間進(jìn)行切換。當(dāng)電網(wǎng)正常時(shí)，機(jī)組運(yùn)行在并網(wǎng)模式。網(wǎng)電故障發(fā)生時(shí)，機(jī)組自動(dòng)切換到孤島模式，機(jī)組保持持續(xù)運(yùn)行不停機(jī)。

In some cases, the unit needs to switch between grid connection and island mode. When the power grid is normal, the unit operates in grid connection mode. In case of grid power failure, the unit will automatically switch to island mode, and the unit will maintain continuous operation without shutdown.

這時(shí)需要注意的是，如果負(fù)荷高于發(fā)電機(jī)組的輸出功率，就需要切斷部分負(fù)荷。機(jī)組控制系統(tǒng)能夠根據(jù)負(fù)荷大小自動(dòng)發(fā)出指令，在負(fù)荷即將超過額定功率時(shí)立即切斷部分負(fù)荷。在設(shè)，需要綜合考慮負(fù)荷的優(yōu)先順序，把非關(guān)鍵負(fù)荷與關(guān)鍵負(fù)荷區(qū)別處理。

At this time, it should be noted that if the load is higher than the output power of the generator set, it is necessary to cut off part of the load. The unit control system can automatically send instructions according to the load size, and cut off part of the load immediately when the load is about to exceed the rated power. In the design, it is necessary to comprehensively consider the priority of loads and treat non critical loads and critical loads differently.

總之呢，燃?xì)獍l(fā)電機(jī)組的控制模式由用戶的需求決定，在具體的控制系統(tǒng)功能的實(shí)現(xiàn)上，廠家根據(jù)機(jī)組數(shù)量，電氣連接方式，以及運(yùn)行方式等配置不同的功能模塊或者控制柜。如有必要，現(xiàn)有的機(jī)組也可以進(jìn)行改造，增減相應(yīng)的配置。更多的相關(guān)內(nèi)容就來我們網(wǎng)站http://www.vw95.cn進(jìn)行咨詢吧！

In a word, the control mode of the gas generator set is determined by the user's needs. In terms of the realization of specific control system functions, the manufacturer configures different functional modules or control cabinets according to the number of units, electrical connection mode, and operation mode. If necessary, the existing units can also be modified to increase or decrease the corresponding configuration. More relevant content will come to our website http://www.vw95.cn Consult!
