GE美國IS200VTURH1BAC輪機控制板是一款專門用于汽輪機控制的模塊，其主要功能和特點可以歸納如下：

一、基本信息

品牌與制造商：GE（美國通用電氣公司）

型號：IS200VTURH1BAC

應用：汽輪機控制系統(tǒng)

二、主要功能

超速保護：

監(jiān)視并測量渦輪機速度，以生成主要超速跳閘信號。這是該控制板的核心功能之一，旨在確保渦輪機在安全速度范圍內(nèi)運行。

控制TRPx端子板上的三個主要超速跳閘繼電器，一旦檢測到超速情況，將立即觸發(fā)緊急電磁閥，以保護渦輪機免受損壞。

軸電流/電壓監(jiān)視：

監(jiān)視軸感應的電壓和電流，并在出現(xiàn)過高水平時發(fā)出警報。這有助于防止電氣故障和機械損壞，確保渦輪機的穩(wěn)定運行。

火焰探測器監(jiān)控：

在燃氣輪機應用中，該控制板還能監(jiān)控八個Geiger-Mueller火焰探測器。這些探測器用于檢測燃燒室中的火焰狀態(tài)，確保燃燒過程的穩(wěn)定性和安全性。

發(fā)電機同步與斷路器控制：

該板上的母線和發(fā)電機電壓將與渦輪機控制器和勵磁系統(tǒng)一起自動同步。同時，它還允許發(fā)電機同步繼電器和主斷路器繼電器線圈的控制，以實現(xiàn)發(fā)電機的精確同步和斷路器的準確控制。

模塊化與冗余設計：

IS200VTURH1BAC支持三重模塊化冗余（TMR）或單工應用。在TMR系統(tǒng)中，它可以提供更高的可靠性和容錯性；而在單工系統(tǒng)中，則能滿足基本的控制需求。

三、技術(shù)特點

高度集成：該控制板集成了多種傳感器、繼電器和控制器，實現(xiàn)了對渦輪機各項參數(shù)的全面監(jiān)控和控制。

精確測量：采用高精度的傳感器和測量電路，確保對渦輪機速度和軸電流/電壓的精確測量。

快速響應：在檢測到異常情況時，能夠迅速生成跳閘信號并觸發(fā)相應的保護措施，防止渦輪機受到進一步損壞。

易于維護：模塊化的設計使得維護和更換部件變得更加方便快捷。

四、應用領(lǐng)域

IS200VTURH1BAC輪機控制板廣泛應用于電力、石化、冶金等行業(yè)的汽輪機控制系統(tǒng)中。在這些領(lǐng)域中，它發(fā)揮著至關(guān)重要的作用，確保了渦輪機的安全、穩(wěn)定和高效運行。

The GE US IS200VTURH1BAC turbine control board is a module specifically designed for turbine control. Its main functions and features can be summarized as follows:

1、 Basic Information

Brand and Manufacturer: GE (General Electric Company)

Model: IS200VTURH1BAC

Application: Steam turbine control system

2、 Main functions

Overspeed protection:

Monitor and measure the turbine speed to generate the primary overspeed trip signal. This is one of the core functions of the control board, aimed at ensuring that the turbine operates within a safe speed range.

Control the three main overspeed trip relays on the TRPx terminal board. Once an overspeed condition is detected, the emergency solenoid valve will be immediately triggered to protect the turbine from damage.

Shaft current/voltage monitoring:

Monitor the voltage and current induced by the axis and issue an alarm when the level is too high. This helps prevent electrical faults and mechanical damage, ensuring the stable operation of the turbine.

Flame detector monitoring:

In gas turbine applications, the control board can also monitor eight Geiger Mueller flame detectors. These detectors are used to detect the flame state in the combustion chamber, ensuring the stability and safety of the combustion process.

Generator synchronization and circuit breaker control:

The bus and generator voltage on this board will be automatically synchronized with the turbine controller and excitation system. At the same time, it also allows for the control of the generator synchronous relay and the main circuit breaker relay coil to achieve precise synchronization of the generator and accurate control of the circuit breaker.

Modular and redundant design:

IS200VTURH1BAC supports triple modular redundancy (TMR) or simplex applications. In TMR systems, it can provide higher reliability and fault tolerance; In a simplex system, it can meet basic control requirements.

3、 Technical features

Highly integrated: This control board integrates multiple sensors, relays, and controllers to achieve comprehensive monitoring and control of various parameters of the turbine.

Accurate measurement: High precision sensors and measurement circuits are used to ensure accurate measurement of turbine speed and shaft current/voltage.

Quick response: When an abnormal situation is detected, it can quickly generate a trip signal and trigger corresponding protective measures to prevent further damage to the turbine.

Easy to maintain: The modular design makes maintenance and component replacement more convenient and efficient.

4、 Application Fields

The IS200VTURH1BAC turbine control board is widely used in turbine control systems in industries such as power, petrochemicals, and metallurgy. In these fields, it plays a crucial role in ensuring the safe, stable, and efficient operation of turbines.
