SPM-D11 Series |
|---|---|
|
The SPM-D11 Series are microprocessor-based synchronizers designed for use on one- or three-phase AC generators equipped with Woodward or other compatible speed controls and automatic voltage regulators. The SPM-D11 Series synchronizers provide automatic frequency, phase, and voltage matching, using either analog or discrete output bias signals. It combines synchronizing for one circuit breaker, load and power factor control, or isochronous load sharing and generator protection. |

DSLC-2 |
|---|---|
|
The Woodward DSLC-2™ (Digital Synchronizer and Load Control) is a microprocessor-based synchronizer and load control designed for use on three-phase AC generators. The DSLC-2 combines synchronizer, load sensor, load control, dead bus closing system, VAR, power factor and process control, all in one powerful package. Applications allow up to 32 generators to be precisely paralleled and controlled. A dedicated Ethernet system provides seamless communications between DSLC-2™ and MSLC-2™ units. A second Ethernet port is provided for customer remote control and monitoring capability using Modbus TCP, and allowing easy DCS and PLC interfacing. Modbus RTU is available through a separate RS-485 port. Woodward used the original solid DSLC combined with an additional decade of application experience, to develop the new DSLC-2. The DSLC-2 excels in either simple generator or complex generator system applications. The DSLC-2/MSLC-2 combination provides multiple unit, segment, utility, and intertie breaker control for complex power systems. |

MSLC-2 |
|---|---|
|
The Woodward MSLC-2™ is a microprocessor based load control designed for three-phase electric power generation sites equipped with our DSLC-2™ (Digital Synchronizer and Load Controls). Woodward combines the original MSLC with a decade of application experience, to develop the new MSLC-2. The MSLC-2™ is a synchronizer, a utility load sensor, an import/export load level control, a power factor control, and a master process control. Applications include power systems which operate in parallel with single- or multiple-utility feeds, as well as new capabilities for multiple segment and intertie breaker control. For utility parallel systems, the MSLC-2 provides either phase matching or slip frequency automatic synchronizing of the local plant bus to the main power grid through one or several main breakers. The MSLC-2’s load sensor and load control sense true RMS power and provide smooth loading and unloading against the power grid. Plant voltage is matched to the utility prior to paralleling. Operating modes can be base load or import/export/process power levels against the utility. Power factor or VAR levels are precisely controlled. The MSLC-2 communicates via Ethernet to control real and reactive loading against the utility by DSLC-2 equipped generators. 32 generators equipped with DSLC-2s can be paralleled to the utility with up to eight individual bus segments. Intertie breakers are controlled and synchronized through individual MSLC-2s actively communicating with the individual DSLC-2s and the other MSLC-2s on the system. For isolated multiple generator systems, the MSLC-2 can be used to operate tie breakers between groups of generators using the DSLC-2 controls. |
