燃?xì)饫?、熱、電分布式能源系統(tǒng)的核心設(shè)備包括燃?xì)獍l(fā)電機(jī)組、吸收式冷(熱)水機(jī)組、余熱鍋爐等。燃?xì)獍l(fā)電機(jī)組設(shè)備包括各種水泵、閥門、冷卻塔、冷卻風(fēng)機(jī)、配電柜等，如何使這些設(shè)備高效、節(jié)能、經(jīng)濟(jì)地運(yùn)行，控制系統(tǒng)是關(guān)鍵，那么，下面一起了解下燃?xì)獍l(fā)電機(jī)組控制系統(tǒng)設(shè)計(jì)要點(diǎn)!

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?xì)獍l(fā)電機(jī)組在運(yùn)行過程中產(chǎn)生兩種能量：電能和熱能。在實(shí)際應(yīng)用中，對(duì)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(xiàng)目中，項(xiàng)目的經(jīng)濟(jì)可行性是一個(gè)重要的方面。必須了解項(xiàng)目的電力需求和熱需求，設(shè)計(jì)發(fā)電機(jī)組經(jīng)濟(jì)的運(yùn)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(dāng)市場上電能的經(jīng)濟(jì)性較好時(shí)，項(xiàng)目申請(qǐng)將以產(chǎn)生更多電能為主要目標(biāo)進(jìn)行設(shè)計(jì)，同時(shí)考慮很大限度地利用余熱。熱能過剩時(shí)排放到空氣中。在項(xiàng)目設(shè)計(jì)中，將以電來定熱;當(dāng)熱能在項(xiàng)目應(yīng)用中的經(jīng)濟(jì)性能良好時(shí)，項(xiàng)目設(shè)計(jì)將滿足用戶所需的熱能為主要需求。在產(chǎn)生熱能的同時(shí)，項(xiàng)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(jì)方法。此類項(xiàng)目申請(qǐng)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(huì)根據(jù)需要設(shè)計(jì)合適的控制系統(tǒng)來控制燃?xì)獍l(fā)電機(jī)組的正常運(yùn)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?xì)饫錈犭姺植际侥茉错?xiàng)目控制系統(tǒng)一般分為四個(gè)功能模塊：顯示模塊、計(jì)算控制模塊、報(bào)警保護(hù)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(gè)設(shè)備都可以按照預(yù)先設(shè)定的工況自動(dòng)運(yùn)行。同時(shí)可將所有運(yùn)行參數(shù)通過數(shù)據(jù)線上傳至上位機(jī)。燃?xì)饫錈犭姺植际侥茉错?xiàng)目控制系統(tǒng)顯示模塊將整個(gè)系統(tǒng)的所有設(shè)備進(jìn)行概覽，通過屏幕直觀顯示所有設(shè)備的運(yùn)行狀態(tài)和運(yùn)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(jì)算與控制模塊：主要通過傳感器計(jì)算系統(tǒng)的運(yùn)行狀態(tài)。并根據(jù)項(xiàng)目要求設(shè)計(jì)所需的目標(biāo)狀態(tài)。將系統(tǒng)的運(yùn)行狀態(tài)與目標(biāo)狀態(tài)進(jìn)行比較后，發(fā)出調(diào)整命令。為保證功能的穩(wěn)定性和準(zhǔn)確性，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(hù)模塊：燃?xì)獍l(fā)電機(jī)組主要功能是當(dāng)系統(tǒng)遇到危險(xiǎn)狀態(tài)時(shí)發(fā)出告警，嚴(yán)重時(shí)自動(dòng)關(guān)閉部分設(shè)備或停止整個(gè)系統(tǒng)，以保護(hù)系統(tǒng)免受更大的損害。系統(tǒng)自動(dòng)停機(jī)的危險(xiǎn)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(yùn)行的數(shù)據(jù)和參數(shù)，以及歷史報(bào)警記錄。通過記錄數(shù)據(jù)分析系統(tǒng)的支持狀態(tài)來計(jì)劃維護(hù)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.
