505 LST  9907-810 WOODWARD 蒸汽涡轮控制器具体包括设计算法和逻辑开始

【产品详情】

505控制器的设计目的是操作所有的工业汽轮机大小和应用。这蒸汽涡轮控制器具体包括设计算法和逻辑开始，停止、控制和保护工业蒸汽轮机或涡轮膨胀机;驱动发电机，压缩机，泵，或工业风扇。

505控制器独特的PID结构使其成为理想的应用程序需要控制蒸汽装置参数如涡轮转速，涡轮负荷、涡轮进口压头压力、排气总管压力，或连接线权力。

控制的特殊pid到pid逻辑允许在正常涡轮运行期间稳定控制

和无颠簸的控制模式转换在工厂扰乱，最大限度地减少过程过或

未达到目标的条件。505控制器通过被动或主动速度感应涡轮速度

通过连接到的一个或两个(分程)执行器探测和控制汽轮机

汽轮机进口蒸汽阀。

505控制器还包括以下涡轮保护功能，以确保水轮机或其驱动负载(压缩机、泵、发电机)不在其外部运行

设计范围:

•3个临界速度避免带

·超速预判和关机保护

可配置欠压或过压停机逻辑

最小和最大速度和负载设置

以太网和串行通信允许用户轻松地将505连接到工厂或

过程控制系统。所有控制器的输入、输出和状态都可以被监控

启动/停止或启用/禁用命令可以通过工业标准Modbus®*给出

TCP或OPC协议。505使用SNTP(同步网络时间协议)over

以太网允许用户同步505的实时时钟到工厂分布式控制

系统。

【英文介绍】

The 505 controller is designed to

Operate all industrial steam turbines

Size and application. The steam

Turbine controllers specifically include

Designing algorithms and logic starts,

Stop, control and protect industry

Steam turbine or turbine expander;

Drive generators, compressors,

Pumps, or industrial fans.

505 controller unique PID structure

The power.

The control's special PID-to-PID logic allows for stable control during normal turbine operation

And bump-free control mode conversion in the plant disrupts, minimizing process overruns or

The condition of not meeting the goal. The 505 controller senses turbine speed by passive or active speed

The turbine is detected and controlled by one or two (split-range) actuators connected to it

Turbine inlet steam valve.

The 505 controller also includes the following turbine protection features to ensure

The turbine or its driving loads (compressors, pumps, generators) do not operate outside it

Design scope:

•3 critical speed avoidance belts

· Overspeed prediction and shutdown protection

Undervoltage or overvoltage shutdown logic can be configured

Minimum and maximum speed and load Settings

Ethernet and serial communication allow users to easily connect the 505 to the factory or

Process control system. The input, output and status of all controllers can be monitored

Start/stop or enable/disable commands can be given via the industry standard Modbus®*

TCP or OPC protocol. 505 Uses SNTP(Synchronous Network Time Protocol)over

Ethernet allows users to synchronize 505's real-time clock to factory distributed control
