燃氣冷、熱、電分布式能源系統(tǒng)的核心設(shè)備包括燃氣發(fā)電機組、吸收式冷(熱)水機組、余熱鍋爐等。燃氣發(fā)電機組設(shè)備包括各種水泵、閥門、冷卻塔、冷卻風(fēng)機、配電柜等，如何使這些設(shè)備、節(jié)能、經(jīng)濟地運行，控制系統(tǒng)是關(guān)鍵，那么，下面一起了解下燃氣發(fā)電機組控制系統(tǒng)設(shè)計要點!

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!

燃氣發(fā)電機組在運行過程中產(chǎn)生兩種能量：電能和熱能。在實際應(yīng)用中，對電能和熱能的需求是不斷變化的。通過排煙系統(tǒng)和冷卻水箱將其排放到空氣中。因此，在分布式能源項目中，項目的經(jīng)濟可行性是一個重要的方面。必須了解項目的電力需求和熱需求，設(shè)計發(fā)電機組經(jīng)濟的運行方案。

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.

當市場上電能的經(jīng)濟性較好時，項目申請將以產(chǎn)生更多電能為主要目標進行設(shè)計，同時考慮很大限度地利用余熱。熱能過剩時排放到空氣中。在項目設(shè)計中，將以電來定熱;當熱能在項目應(yīng)用中的經(jīng)濟性能良好時，項目設(shè)計將滿足用戶所需的熱能為主要需求。在產(chǎn)生熱能的同時，項目中多余的電能將通過市電并網(wǎng)的方式輸送至城市電網(wǎng)。這就是火電的設(shè)計方法。此類項目申請需要與市電力部門協(xié)調(diào)，取得上網(wǎng)許可。在確定是用熱定電還是電定熱后，我們會根據(jù)需要設(shè)計合適的控制系統(tǒng)來控制燃氣發(fā)電機組的正常運行。

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.

燃氣冷熱電分布式能源項目控制系統(tǒng)一般分為四個功能模塊：顯示模塊、計算控制模塊、報警保護模塊和數(shù)據(jù)記錄模塊。

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)顯示模塊：現(xiàn)代設(shè)備都有自己的控制系統(tǒng)。任何單個設(shè)備都可以按照預(yù)先設(shè)定的工況自動運行。同時可將所有運行參數(shù)通過數(shù)據(jù)線上傳至上位機。燃氣冷熱電分布式能源項目控制系統(tǒng)顯示模塊將整個系統(tǒng)的所有設(shè)備進行概覽，通過屏幕直觀顯示所有設(shè)備的運行狀態(tài)和運行參數(shù)。

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)計算與控制模塊：主要通過傳感器計算系統(tǒng)的運行狀態(tài)。并根據(jù)項目要求設(shè)計所需的目標狀態(tài)。將系統(tǒng)的運行狀態(tài)與目標狀態(tài)進行比較后，發(fā)出調(diào)整命令。為保證功能的穩(wěn)定性和性，建議控制系統(tǒng)采用雙閉環(huán)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)告警保護模塊：燃氣發(fā)電機組主要功能是當系統(tǒng)遇到危險狀態(tài)時發(fā)出告警，嚴重時自動關(guān)閉部分設(shè)備或停止整個系統(tǒng)，以保護系統(tǒng)免受更大的損害。系統(tǒng)自動停機的危險狀態(tài)有：水溫高、油壓低、超速、爆缸、漏氣等。4)數(shù)據(jù)記錄模塊：用于記錄系統(tǒng)運行的數(shù)據(jù)和參數(shù)，以及歷史報警記錄。通過記錄數(shù)據(jù)分析系統(tǒng)的支持狀態(tài)來計劃維護和保養(yǎng)。

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.
