燃气冷、热、电分布式能源系统的核心设备包括燃气发电机组、吸收式冷(热)水机组、余热锅炉等。燃气发电机组设备包括各种水泵、阀门、冷却塔、冷却风机、配电柜等，如何使这些设备高效、节能、经济地运行，控制系统是关键，那么，下面一起了解下燃气发电机组控制系统设计要点!

The core equipment of the distributed energy system for gas cooling, heating, and electricity includes gas generator units, absorption cooling (heating) water units, waste heat boilers, etc. Gas generator set equipment includes various water pumps, valves, cooling towers, cooling fans, distribution cabinets, etc. How to make these equipment operate efficiently, energy-efficient, and economically is the key to the control system. So, let's learn about the key points of gas generator set control system design together!

燃气发电机组在运行过程中产生两种能量：电能和热能。在实际应用中，对电能和热能的需求是不断变化的。通过排烟系统和冷却水箱将其排放到空气中。因此，在分布式能源项目中，项目的经济可行性是一个重要的方面。必须了解项目的电力需求和热需求，设计发电机组经济的运行方案。

Gas generator sets generate two types of energy during operation: electrical energy and thermal energy. In practical applications, the demand for electrical and thermal energy is constantly changing. Discharge it into the air through the smoke exhaust system and cooling water tank. Therefore, in distributed energy projects, the economic feasibility of the project is an important aspect. It is necessary to understand the power and heat demands of the project and design an economical operation plan for the generator set.

当市场上电能的经济性较好时，项目申请将以产生更多电能为主要目标进行设计，同时考虑很大限度地利用余热。热能过剩时排放到空气中。在项目设计中，将以电来定热;当热能在项目应用中的经济性能良好时，项目设计将满足用户所需的热能为主要需求。在产生热能的同时，项目中多余的电能将通过市电并网的方式输送至城市电网。这就是火电的设计方法。此类项目申请需要与市电力部门协调，取得上网许可。在确定是用热定电还是电定热后，我们会根据需要设计合适的控制系统来控制燃气发电机组的正常运行。

When the economy of electricity in the market is good, the project application will be designed with the main goal of generating more electricity, while considering the maximum utilization of waste heat. When there is excess heat energy, it is discharged into the air. In project design, electricity will be used to determine heat; When the economic performance of thermal energy in project applications is good, the project design will mainly meet the thermal energy needs of users. At the same time as generating thermal energy, the excess electrical energy in the project will be transmitted to the urban power grid through grid connection. This is the design method for thermal power. This type of project application requires coordination with the municipal power department and obtaining internet access permission. After determining whether to use thermal or electrical heating, we will design a suitable control system according to the needs to control the normal operation of the gas generator set.

燃气冷热电分布式能源项目控制系统一般分为四个功能模块：显示模块、计算控制模块、报警保护模块和数据记录模块。

The control system of gas cooling, heating and power distributed energy projects is generally divided into four functional modules: display module, calculation control module, alarm protection module, and data recording module.

1)显示模块：现代设备都有自己的控制系统。任何单个设备都可以按照预先设定的工况自动运行。同时可将所有运行参数通过数据线上传至上位机。燃气冷热电分布式能源项目控制系统显示模块将整个系统的所有设备进行概览，通过屏幕直观显示所有设备的运行状态和运行参数。

1) Display module: Modern devices have their own control systems. Any individual device can automatically operate according to pre-set operating conditions. At the same time, all operating parameters can be uploaded to the upper computer through a data cable. The display module of the distributed energy project control system for gas cooling, heating and power provides an overview of all equipment in the entire system, and visually displays the operating status and parameters of all equipment through the screen.

2)计算与控制模块：主要通过传感器计算系统的运行状态。并根据项目要求设计所需的目标状态。将系统的运行状态与目标状态进行比较后，发出调整命令。为保证功能的稳定性和准确性，建议控制系统采用双闭环控制。

2) Calculation and control module: mainly calculates the operating status of the system through sensors. And design the required target states according to project requirements. After comparing the running state of the system with the target state, issue an adjustment command. To ensure the stability and accuracy of the function, it is recommended to use dual closed-loop control for the control system.

3)告警保护模块：燃气发电机组主要功能是当系统遇到危险状态时发出告警，严重时自动关闭部分设备或停止整个系统，以保护系统免受更大的损害。系统自动停机的危险状态有：水温高、油压低、超速、爆缸、漏气等。4)数据记录模块：用于记录系统运行的数据和参数，以及历史报警记录。通过记录数据分析系统的支持状态来计划维护和保养。

3) Alarm protection module: The main function of a gas generator set is to issue an alarm when the system encounters a dangerous state, and in severe cases, automatically shut down some equipment or stop the entire system to protect the system from greater damage. The dangerous states of automatic shutdown of the system include high water temperature, low oil pressure, overspeed, cylinder explosion, air leakage, etc. 4) Data recording module: used to record system operation data and parameters, as well as historical alarm records. Plan maintenance and upkeep by recording the support status of the data analysis system.
