在我國,由于受到天然氣供應的影響,天然氣發(fā)電尚處于初始階段。大面積的天然氣發(fā)電作為分布能源站還要假以時日。現(xiàn)在的小規(guī)模800kw燃氣發(fā)電機組發(fā)電主要是在油田、氣田以及機場、酒店等。可以預計,隨著天然氣供應的愈加充足、供應范圍的不斷擴大,近幾年天然氣發(fā)電將會受到一個飛速的發(fā)展。
In China, due to the impact of natural gas supply, natural gas power generation is still in its initial stage. The large-scale natural gas power generation as a distributed energy station will take some time. The small-scale 800kw gas generator set currently generates electricity mainly in oil fields, gas fields, airports, hotels, etc. It can be expected that with the increasing supply of natural gas and the continuous expansion of the supply range, natural gas power generation will experience rapid development in recent years.
800kw燃氣發(fā)電機組具有輸出功率范圍廣,啟動和運行可靠高、發(fā)電質(zhì)量好、重量輕、體積小、維護簡單、低頻噪聲小等優(yōu)點,一般它們具有以下三個優(yōu)點:
800kw gas generator units have the advantages of wide output power range, high reliability in startup and operation, good power generation quality, light weight, small size, simple maintenance, and low low-frequency noise. Generally, they have the following three advantages:
一是發(fā)電質(zhì)量好。由于800kw燃氣發(fā)電機組工作時只有旋轉運動,電調(diào)反應速度快,工作特別平穩(wěn),發(fā)電機輸出電壓和頻率的精度高,波動小,在突加空減50%和75%負載時,機組集腋成裘駝行非常穩(wěn)定。優(yōu)于柴油發(fā)電機組的電氣性能指標。
One is good power generation quality. Due to the fact that the 800kw gas generator unit only operates in rotational motion, the electrical regulation response speed is fast, and the operation is particularly stable. The accuracy of the generator output voltage and frequency is high, and the fluctuation is small. When suddenly adding 50% and 75% of the load, the unit operates very stably. It is superior to the electrical performance index of diesel generator set.
二是啟動性能好,啟動成功率高。從冷態(tài)啟動成功后到滿負載的時間僅為30秒鐘,而國際規(guī)定柴油發(fā)電機啟動成功后3分鐘帶負載。800kw燃氣發(fā)電機組可以任何環(huán)境溫度和氣候下保證啟動的成功率。
Secondly, it has good startup performance and a high success rate. The time from successful cold start to full load is only 30 seconds, while the international regulations require that diesel generator be loaded 3 minutes after successful start. The 800kw gas generator unit can ensure the success rate of startup under any environmental temperature and climate.
三是噪聲低振動小。800kw燃氣發(fā)電機組由于燃汽輪機處于高速旋轉狀態(tài),它的振動非常小,而且低頻噪聲優(yōu)于柴油發(fā)電機組。
The third is low noise and low vibration. 800 kw gas generator set has very low vibration and low frequency noise better than diesel generator set due to the high speed rotation of gas turbine.
