Description

ABB CMA130 3DDE300410 SYNPOL‑D Generator Synchronizer & Load‑Sharing Controller

 

Product Details

CMA130, order code 3DDE300410, is panel‑mount integrated automatic synchronisation and load‑sharing controller for synchronous generators, part of ABB SYNPOL‑D product line, commonly paired with Unitrol excitation systems for power‑plant generator sets。Origin: Switzerland. Lifecycle status: EOL discontinued, OEM new production stopped; market supply includes NOS surplus and fully‑tested refurbished spare‑parts。

‑ Form factor: Panel‑mount embedded unit, complete integrated controller with LCD display and keypad operator interface ‑ Power supply: 110‑240 VAC main supply, optional 24 VDC backup power ‑ Measurement inputs: 3‑phase PT voltage (generator & busbar), 3‑phase CT current, circuit‑breaker status contact, speed/frequency signal ‑ Synchronisation functions: auto synchronisation; adjustable ΔV, Δf, phase‑angle closing window; advance closing time setting for generator breaker ‑ Load‑control modes: Isochronous load‑sharing and droop load‑sharing for parallel multi‑generator operation; active/reactive power regulation ‑ Control outputs: Raise/lower governor speed signals (relay contact / 4‑20 mA); generator breaker close command; raise/lower excitation set‑point signals ‑ Communication: Serial / bus interface for connection to ABB Unitrol 5000/6000 excitation, AC800M / AC800PEC and plant DCS ‑ Mounting: Cabinet front‑panel cut‑out installation ‑ Operating temperature: ‑20℃ ~ +60℃, humidity 5‑95 % non‑condensing, IP20 front‑panel ‑ Weight: approx 1.0 kg

 

Applications

Key Features

  1. All‑in‑one panel‑mount SYNPOL‑D controller providing automatic synchronisation and multi‑unit load‑sharing for synchronous generators.
  2. Configurable synchronisation thresholds for voltage, frequency and phase‑angle; optimised generator‑breaker advance closing timing.
  3. Supports both isochronous zero‑droop and droop‑mode parallel load‑sharing for active and reactive power distribution.
  4. Built‑in LCD and keypad for local parameter setup, real‑time measurement display, alarm and event diagnostics.
  5. Relay and analog outputs to governor and excitation system for speed‑control and voltage‑set‑point adjustment.
  6. Native interface to ABB Unitrol excitation and AC800PEC / AC800M control platforms; data exchange with plant DCS.
  7. Comprehensive self‑diagnosis for PT/CT faults, synchronisation‑timeout and abnormal operating‑condition alarm outputs.
  8. Manufactured in Switzerland; EOL obsolete, only NOS or fully‑tested refurbished spare‑parts available.

 

Main Functions

  1. Measure generator and bus‑bar voltage, frequency and phase angle, execute automatic synchronisation and issue generator‑breaker close command within allowed tolerance window.
  2. Implement isochronous or droop‑based active‑power and reactive‑power load‑sharing among multiple parallel‑running generators.
  3. Output raise/lower speed commands to turbine/governor and raise/lower set‑point signals to excitation system for frequency‑voltage regulation.
  4. Display real‑time electrical measurements, synchronisation status, alarms and fault events via local front‑panel HMI.
  5. Detect synchronisation time‑out, PT/CT signal‑loss and abnormal conditions, generate alarm interlock signals.
  6. Exchange set‑points, measurements and status data with Unitrol excitation controller and upper‑level DCS system.
  7. Cooperate with governor, excitation power stack and generator‑set to complete grid‑paralleling and parallel‑operation control.
  8. Serve as generator synchronisation & load‑sharing control unit for power‑station applications.
