ABB IMHSS03 液压伺服模块

IMHSS03 液压伺服模块是 INFI 90® 系统中用于控制涡轮机转速的阀门位置控制模块。它将伺服阀或 I/H 转换器连接到 IMMFP01、IMMFP02 或 IMMFP03 多功能处理器模块。

多功能处理器 （MFP） 模块通过向液压伺服 （HSS） 模块发送位置要求来控制蒸汽或燃气轮机节流阀的位置。HSS 模块驱动其输出以打开或关闭节流阀，以满足位置需求。

多功能数码复合机模块使用IMFCS01频率计数器模块来测量涡轮机转速。频率计数器模块通过计算和定时来自涡轮轴上磁性拾音器的脉冲来测量涡轮速度。多功能数码复合机模块使用此计数来计算涡轮机转速，并根据设定点计算新需求。多功能处理器(MFP) 模块通过向液压伺服 (HSS) 模块发送位置要求来控制蒸汽或燃气轮机节流阀的位置。HSS 模块驱动其输出以打开或关闭节流阀，以满足位置需求。

该应用说明了 PLC 用户开始采用基于 PLC 的控制系统架构是多么简单，”ABB 自动化产品部机械控制和自动化产品经理 Knud Jansen 说。“NTK 的关键驱动因素是使用高级结构化文本语言进行编程的能力，以及强大的代码分析器工具——这为公司的软件开发人员在开发和测试 PLC 代码模块时提供了即时反馈。”
NTK 的 PLC 起重机控制系统安装在位于驾驶室内的受保护机柜中。然而，PLC 同样可以在“***条件”变体中提供，允许用户配置功能 PLC 解决方案，这些解决方案也***，适合在恶劣条件和***气候下运行——这在一些起重机和绞车应用中很常见例如。

The IMHSS03 hydraulic servo module is a valve position control module for controlling turbine speed in the INFI 90® system. It connects the servo valve or I/H converter to the IMMFP01, IMMFP02 or IMMFP03 multifunctional processor module.

The Multi-function processor (MFP) module controls the position of the steam or gas turbine throttle by sending position requirements to the hydraulic servo (HSS) module. The HSS module drives its output to open or close the throttle to meet the position requirements.

The multifunctional digital composite module uses the IMFCS01 frequency counter module to measure turbine speed. The frequency counter module measures turbine speed by counting and timing pulses from magnetic pickups on the turbine shaft. The multifunctional digital composite module uses this count to calculate turbine speed and calculate new requirements based on set points.

This application illustrates how easy it is for PLC users to start adopting PLC-based control system architectures, “said Knud Jansen, Product Manager, Machine Control and Automation, ABB Automation Products. “The key drivers of NTK are the ability to program in a high-level structured text language, as well as powerful code analyzer tools – which provide the company’s software developers with immediate feedback as they develop and test PLC code modules.”
NTK’s PLC crane control system is installed in a protected cabinet located in the cab. However, PLCS are equally available in “best conditions” variants, allowing users to configure functional PLC solutions that are also best suited to operate in harsh conditions and best climates – this is common in some crane and winch applications, for example.
