Woodward 8280-1056 冗余负载分配的数字控制单元

【产品详情】

8280-1056 是用于冗余负载分配的数字控制单元。该装置是伍德沃德 723PLUS 数字控制系列中的可用型号之一，通过公司的数字通信介质“控制 LON”进行负载共享。通过使用两个 LON 端口实现冗余，每个 LON 网络上重复数据。

723PLUS 型号 8280-1056 支持在最多 2 辆总线上为多达 6 台发动机分配负载。要使系统正常工作，每个引擎都需要一个唯一的 LON 地址。通过 LON 网络连接交换有四个主要参数：

发电机 kW 负载 %

总线决胜局状态

发电机断路器状态

通过离散输入 E 或软件设置选择总线

该装置提供的控制功能包括速度感应、速度控制、速度参考、燃油限制器（启动燃油限制器和最大燃油限制器）、辅助输出（三个 4-20mA）、发电机控制（同步和下降）、跳跃速率限制器、警报和负载分配（通过 LON）。

8280-1056 控制器上的速度感应由一个或两个速度传感器完成。这些传感器可以是磁性拾取器（MPU）或接近探头。如果检测到超速（高于 2000 rpm）或低于速度 （15 rpm） 情况，则由 LED 指示速度故障。723PLUS 控制器上有两种类型的警报：主要警报和次要警报。超速情况和两个速度传感器的故障总是会触发重大警报。

【英文介绍】

The 8280-1056 is a digital control unit for redundant load distribution. The unit is one of the available models in the Woodward 723PLUS digital control family, with load sharing via the company's digital communication medium "Control LON". Redundancy is achieved through the use of two LON ports, with repeated data on each LON network.

723PLUS models 8280-1056 support load distribution for up to 6 engines on up to 2 buses. For the system to work properly, each engine needs a unique LON address. There are four main parameters for connecting to the exchange over the LON network:

Generator kW load %

Bus tiebreaker status

Generator breaker condition

Select the bus by discrete input E or software Settings

The control functions provided by the unit include speed sensing, speed control, speed reference, fuel limiter (starting fuel limiter and maximum fuel limiter), auxiliary output (three 4-20mA), generator control (synchronization and descent), jump rate limiter, alarm, and load distribution (via LON).

The speed sensing on the 8280-1056 controller is done by one or two speed sensors. These sensors can be magnetic pickers (MPUs) or proximity probes. If overspeed (above 2000 rpm) or underspeed (15 rpm) conditions are detected, a speed fault is indicated by the LED. There are two types of alarms on the 723PLUS controller: primary alarm and secondary alarm. Overspeed conditions and the failure of two speed sensors always trigger major alarms.

For more information about the 723PLUS Model 8280-1056 controller, including I/O details and configurable parameters, see Woodward Application Manual 26310 and Hardware Manual 02877.
