8273-126  2301D数字负载共享 和发动机速度控制

Woodward 2301D控制由柴油或气体发动机驱动的发电机的负载分担和速度。(这些电源在本手册中被称为“原动机”。)2301D是一种基于微处理器的数字控制，设计包括2301A负载共享控制的功能并与之兼容。软件灵活性的提高使2301D能够包括在以前版本的2301A控制系统中需要额外设备的控制功能。因此，2301D适合升级现有的

控制系统或在新安装中增加功能。

控制装置安装在一个金属板底盘上，由一块印刷电路板组成。2301D通过控制前端的9针连接器连接的外部计算机进行设置和配置。组态软件随每个控件一起提供。

2301D提供同步、下垂或基本负载控制。该2301D将允许软负载转移时，添加或从总线移除。

等时模式用于恒定原动机速度:

·单原动机操作或

在隔离总线上由Woodward负载共享控制系统控制的两个或多个原动机

下垂模式用于速度控制，作为负载的函数，具有:

单原动机运行在无限总线或

The Woodward 2301D controls load sharing and speed of generators driven by diesel or gaseous engines. (These power sources are referred to as “prime movers” throughout this manual.) The 2301D is a microprocessor-based digital control designed to include the functions of and be compatible with 2301A load sharing controls. The increased flexibility of software allows the 2301D to include control functions that required additional equipment in previous versions of 2301A control systems. The 2301D therefore is suitable for upgrading existing

control systems or increased functionality in new installations.

The control is housed in a sheet-metal chassis and consists of a single printed circuit board. The 2301D is set up and configured through an external computer connected at the 9-pin connector at the front of the control. The configuration software is supplied with each control.

The 2301D provides control in either isochronous, droop, or base load. The 2301D will allow for soft load transfer when being added to or removed from a bus.

The isochronous mode is used for constant prime mover speed with:

 Single prime mover operation or

 Two or more prime movers controlled by Woodward load sharing control systems on an isolated bus

The droop mode is used for speed control as a function of load with:

 Single prime mover operation on an infinite bus or

 Parallel operation of two or more prime movers

The base load mode provides constant load level operation against a bus with the load controlled by the 2301D.

 The load setting is set by a fixed reference,

 or an external input analog input,

 or external contact control of the reference.

The 2301D Control Hardware includes:

 1 Load Sensor

 1 Actuator Driver

 1 MPU Speed Sensor

 1 Configurable Analog Output

 2 Configurable Analog Inputs

 8 Discrete (Switch) Inputs

 4 Discrete (Relay Driver) Outputs

The following is an example of the typical hardware needed for a 2301D system controlling a single prime mover and generator:

 A 2301D electronic control

 An external 18 to 40 Vdc power source

 A speed-sensing device

 A proportional actuator to position the fuel-metering device and

 Current and potential transformers for measuring the load carried by the generator
