9905-355 交流发电机控制 有助于无颠簸负载转移

【产品详情】

伍德沃德 DSLC 系列模块是专为交流发电机控制和同步而构建的设备系列的一部分。这些装置均由伍德沃德公司开发和生产。该装置特别被指定为伍德沃德 DSLC 的 9905-355 装置。

DSLC单元提供的标准功能包括相位匹配、跳差频率同步、电压匹配和自动死总线闭合的可选功能。自动发电机装卸有助于无颠簸负载转移。有三种不同的控制功能;下垂、基本负载和同步负载。这些装置能够对热电联产、进出口和压力控制进行过程控制，以及安装的交流发电机等。

9905-355 模块配备了多个多功能、完全可调的上限和下限报警器，以及一个带继电器驱动器输出端子的负载开关。数字通信网络能够提供在单元之间共享多种功能的能力，例如负载共享、VAR/PF 共享和数据交换。

9905-355 装置的操作规格包括介于极端之间的温度范围。该模块可以承受的最冷温度为-40°C，它可以承受高达70°C的热阈值。湿度产生的过量水蒸气会导致设备元件内部发生腐蚀，该型号可处理高达 95% 的相对湿度。

【英文介绍】

The Woodward Model 9905-354 is a microprocessor-based DSLC digital synchronizer and load control. When used with Woodward speed controllers and automatic voltage regulators, the controller is designed to parallel, synchronize, load and unload three-phase generator sets.

Some of the features of the 9905-354 include:

Built-in diagnosis

Setup, metering and diagnostic functions are achieved through a handheld programmer terminal

Generator automatic handling

Voltage drop, base load and synchronous load control functions

Reverse power relay.

The 9905-354 provides phase matching or slip frequency synchronization. The actual slip frequency and circuit breaker delay values of the two methods are used to predict the minimum phase difference between the generator and the bus when the actual circuit breaker is closed. The controller has automatic dead bus closure function, where only one DSLC control is granted dead bus closure permission through locking technology on the communication network.

Other synchronizer features that may be enabled or disabled during installation include:

Delay automatic multi-color reclosing

Voltage matching

Automatic resynchronization

Synchronizer timeout alarm

When using the 9905-354 DSLC controller, the internal digital base load reference can be raised or lowered by switching input. Remote load Settings are possible with 4-20 mA analog inputs. Loading and unloading ramps ensure smooth transition when operating mode changes.

To prevent static damage, you should follow certain precautions when using or near the controller, such as touching and holding grounded metal objects (pipes, cabinets, equipment, etc.) to release static electricity from your body to the ground before performing maintenance on the DSLC, wearing natural fiber clothing while performing maintenance on the controller, and maintaining the DSLC. And keep plastic, vinyl, and styrofoam materials as far away from controllers, modules, and work areas as possible.
