使用两个以太网端口可以实现冗余以太网网络。

伍德沃德利用原有的固体 DSLC 结合十年的应用经验，开发了新的 DSLC-2。DSLC-2 在简单的发生器或复杂的发生器系统应用中表现出色。DSLC-2/MSLC-2 组合为复杂的电力系统提供多单元、分段、公用设施和联网断路器控制。

功能包括：

专用以太网网络可在所有 DSLC-2 和 MSLC-2 之间实现精确的系统通信，从而减少系统布线。

以太网 Modbus TCP 和 Modbus RTU，用于远程控制和监控。

冗余以太网通信，增强可靠性。

“系统更新”功能允许移除或添加发电机组。

新的 DSLC-2 可以针对多种应用进行配置。

集成的 DSLC-2 和 MSLC-2 系统功能消除了对连接到单个模块（如负载传感器和同步器）的冗余传感器（如 PT、CT 和 MOP）的需求。

后面板安装和缩小的尺寸释放了门空间，并提供了易于布线。

无需额外的继电器逻辑来控制死总线闭合。

同步器和负载控制之间的转差频率并联、电压匹配和速度偏置传输可实现平滑并联，而不会出现反向功率跳闸的风险。

三相真有效值功率检测使 DSLC-2 控制即使在相位负载和电压波动不平衡的情况下也能准确无误。

当系统中包含变压器时，GCB的相位角校正。

伍德沃德工具包™软件允许使用与原始 DSLC 相同的基本菜单树和概览屏幕进行灵活设置。发电机和母线参数的图形概览以及趋势分析使 DSLC-2 调试变得友好。所有伍德沃德设备都可以通过一次连接到网络进行编程。

ToolKit 可以通过其中一个以太网端口或通过 RS-232 端口访问。

Features and functions

Woodward DSLC-2 (Digital Synchronizer and Load Control) is a microprocessor-based synchronizer and load control designed for use in three-phase alternators. DSLC-2 integrates synchronizer, load sensor, load control, dead bus closure system, VAR, power factor and process control in one powerful package.

Applications allow for precise parallel and control of up to 32 generators. A dedicated Ethernet system provides seamless communication between DSLC-2 and MSLC-2 units. DCS and PLC interfaces are easily implemented by providing a second Ethernet port for customers to remotely control and monitor using Modbus TCP. Modbus RTU can be used via a separate RS-485 port.

Redundant Ethernet networks can be implemented using two Ethernet ports.

Woodward developed the new DSLC-2 using the original solid DSLC combined with ten years of application experience. The DSLC-2 performs well in simple generator or complex generator system applications. The DSLC-2/MSLC-2 combination provides multi-unit, segmented, utility and networked circuit breaker control for complex power systems.

Features include:

A dedicated Ethernet network enables precise system communication between all DSLC-2 and MSLC-2, thereby reducing system cabling.

Ethernet Modbus TCP and Modbus RTU for remote control and monitoring.

Redundant Ethernet communication for enhanced reliability.

The System Update feature allows you to remove or add a generator set.

The new DSLC-2 can be configured for a variety of applications.

The integrated DSLC-2 and MSLC-2 system capabilities eliminate the need for redundant sensors such as PT, CT, and MOP connected to a single module such as load sensors and synchronizers.

The rear panel mount and reduced size frees up door space and provides easy wiring.

No additional relay logic is required to control dead bus closure.

Paralleling of slip frequency, voltage matching and speed bias transmission between synchronizer and load control enables smooth paralleling without the risk of reverse power tripping.

Three-phase true RMS power detection enables DSLC-2 control to be accurate even when the phase load and voltage fluctuations are unbalanced.

When a transformer is included in the system, the phase Angle of the GCB is corrected.

The Woodward Toolkit ™ software allows for flexible setup using the same basic menu tree and overview screen as the original DSLC. A graphical overview of generator and bus parameters and trend analysis make DSLC-2 commissioning friendly. All Woodward devices can be programmed with a single connection to the network.

The ToolKit can be accessed through one of the Ethernet ports or through the RS-232 port.

DSLC-2 integrates synchronizer, load sensor, load control, dead bus closure system, VAR, power factor and process control in one powerful package.

In developing the new DSLC-2, Woodward combined the original solid DSLC with another decade of application experience. The Digital Synchronizer and Load Control-2 series or DSLC-2 units are designed for a variety of different applications and functions. These units are designed for standard three-phase alternator systems. The DSLC series is equipped with a combination of synchronizers, load control units and sensors.

Other features included with the system include Ethernet Modbus TCP, which provides accurate grid system communication between connected synchronizers. The 8440-1878 is a 5 amp version of DSLC-2 with a current transformer (CT) input terminal.
