在分布式能源项目中，燃气发电机组是其重要的组成部分，燃气发电机组选型目标是选择一款与项目应用相匹配，在项目应用中经济性的设备。接下来简单讲一下选型时需要考虑的指标有哪些？

In the distributed energy project, the gas generator set is an important component. The selection goal of the gas generator set is to select a device that matches the project application and is economical in the project application. Next, let's talk about the indicators that need to be considered when selecting models?

1，框架性参数

1. Frame parameters

燃气发电机组使用范围和使用方式；燃气发电机组型号、输出电压、频率、适用燃气的品质、排放指标、低温冷却水进水温度和高温冷却水出口温度等。

Scope and mode of use of gas-fired generating units; Model, output voltage, frequency, quality of applicable gas, emission index, inlet temperature of low-temperature cooling water and outlet temperature of high-temperature cooling water of gas-fired generator set.

2，燃气消耗指标

2. Gas consumption index

燃气消耗量或发电效率，余热利用效率对于项目的投资回收周期，发电成本有着至关重要的作用。

Gas consumption or power generation efficiency and waste heat utilization efficiency play a vital role in the investment recovery cycle and power generation cost of the project.

3，发动机指标

3. Engine index

燃气发电机组核心是燃气发动机，燃气发动机性能至关重要。燃气发动机的技术参数包括：生产商、发动机缸数、缸径、冲程、排量、吸气方式、机械输出功率、汽缸平均压力、额定转速、压缩比、润滑油消耗量、要求燃气的工作压力及所能适用的燃料较小甲烷值、启动方式和发电机组尺寸和重量。

The core of gas generator set is gas engine, and the performance of gas engine is very important. The technical parameters of the gas engine include: manufacturer, engine cylinder number, cylinder diameter, stroke, displacement, suction mode, mechanical output power, average cylinder pressure, rated speed, compression ratio, lubricating oil consumption, working pressure of the required gas and the smaller methane value of the applicable fuel, starting mode, size and weight of the generator set.

4，热平衡指标

4. Heat balance index

在分布式能源项目中，余热利用是项目的另一个重要组成部分，燃气发电机组热平衡指标是项目余热利用设计的基础。

In distributed energy projects, waste heat utilization is another important part of the project, and the heat balance index of gas generator set is the basis of waste heat utilization design of the project.

5，进排气指标

5. Intake and exhaust indexes

燃气发动机所允许的进气阻力和排气阻力、温度和流量是机房通风设计及排烟系统余热利用设计中的重要参数。所有机房通风设计、余热利用等须满足发电机组满载运行的要求。

The allowable intake and exhaust resistance, temperature and flow of gas engine are important parameters in the ventilation design of machine room and the waste heat utilization design of exhaust system. The ventilation design and waste heat utilization of all machine rooms must meet the requirements of full load operation of the generator unit.

6，功率折损

6. Power loss

发动机功率折损是燃气发电机组一个非常重要的参数。它反映了发动机在不同海拔和不同气温下燃气发动机能够输出的实际功率。

Engine power loss is a very important parameter of gas generator set. It reflects the actual power that the gas engine can output at different altitudes and temperatures.
