Multilin™ D25 Substation Controller Substation Automation and Control in one Box GE’s D25 is a scalable, flexible, modular, and upgradable automation controller, suitable for both large and small substation automation projects in either new or retrofit situations. The D25 provides the tools and flexibility necessary to create customized automation and control applications including; communications & data concentrator, automation controller, metering & sequence of events fault recording, and transformer monitoring & control. Key Benefits • Replaces multiple devices with a single unit. It’s unified design reduces wiring and maintenance costs • Retrieves data from legacy and third-party devices and runs diagnostics of primary equipment expanding future physical and functional station requirements • It can be equipped with two different built-in screens 1). Data Display Panel to show status of different points (digital or analog) to the operator and 2). Graphical Display Panel (GDP) allowing users to configure dynamic displays with one-line diagrams and alarm screens • Measures and records total harmonic distortion, harmonic spectrum, RMS trending, RMS profiling, voltage sags, swells and interruptions, allowing operators and analysts to examine the consistency of power going through the system and pinpoint problem area • Transfers fault records automatically via a LAN to the substation computer or directly to a remote PC through email ensuring relay settings are correct Applications • Transmission substations – runs applications including interlocking, advanced load shedding, and fault recording via IEC® 61850 GOOSE through a dual redundant Ethernet • Distribution substations – handles all the automation • Generator substations – monitors and automates large set-up transformers and integrates transformer sensor data within existing SCADA systems Automation and Control • Provides synchronism check including bypass function • Monitors voltage difference, phase angle difference, and slip frequency • Supports multiple buses per feeder allowing for dual-busbar schemes • Auto restoration accommodating up to 255 concurrent restorations • Built in LogicLinx®, an IEC 61850 compliant editing/debugging tool • Extensive, configurable alarming capability for AC analog values Power Quality Metering • Records oscillography files including 1, 2, 2 ½, and 3 element metering • Digital fault recording up to 16 MB of fault data locally • Harmonic values (up to the 21st) on every AC Analog input • Monitors power quality profile RMS values for up to 6 AC circuits • Fully functional local HMI • Records AC analog values and stores them in COMTRADE format Flexible I/O • Modular system allows an easy increase in I/O capability • Accommodates up to 96 digital inputs, 32 digital outputs, 32 analog inputs (DC) and 15 AC i

Flexible Substation Communications & Control Enterprise Systems CT/VT Connections Status Control Device Communications Dynamic Bus Switching The D25 supports multiple buses per feeder, where each bus is defined by a set of PTs and a digital input (referred to as Active Bus Indication) that indicates when the bus is active on that feeder. The D25 monitors the Active Bus Indications to determine which set of PTs to use for the feeder. This unique ability allows for dual-busbar schemes to be reconfigured dynamically, maintaining a system-metering scheme without requiring an external voltage...

software captures current and voltage waveforms as well as status from analog and digital channels. Up to 250 digital status inputs can be recorded and combined with 240 cycles of waveform data in standard COMTRADE files. The software stores up to 16 MB of fault data locally for subsequent retrieval via multiple protocols such as TFTP or DNP3. Harmonic Spectrum The D25 can provide harmonic values (up to the 21st) on every AC Analog input and make it available to a control center. Values such as total harmonic distortion are also calculated and made available. Power Quality The D25 can...

Digital Inputs 96 inputs are available with chatter filter to eliminate unwanted alarms. Single-point, double-point and accumulators can be configured using digital inputs. The wetting voltage of digital inputs can also be selected to meet site-specific requirements. Manage Redundant I/O The D25 is capable of managing redundant I/O based on the operational status of each device. The D25 can also maintain control functionality by redirecting a command to the final destination. This feature is unique within the GE Digital Energy suite of devices and allows for an easier integration with...
