SID-2320

Smart Synchronization Controller

The SID-2320M Microgrid Synchronization Controller is a grid-connected and islanding switching control device specially developed for hybrid power microgrids composed of small and medium-sized synchronous generator sets (such as gas turbines and hydro turbine units) and power electronic converters.

It is applicable to differential-frequency synchronization between two independent power sources and microgrid grid-connected/islanding switching scenarios.

It is widely applicable in PV-storage-diesel microgrids, PV-storage microgrids, PV-storage-charging stations, and islands/remote areas without grid access.

KEY Features

1

Real‑time Fault Detection & Seamless Islanding Transition

Real-time detection algorithms based on voltage transient characteristics quickly identify utility power faults and disconnect the circuit breaker to achieve seamless islanding transition.
2

Zero‑phase‑angle Impact‑free Synchronization

Based on an accurate mathematical control model, the system reliably captures the first available grid connection opportunity and achieves impact-free synchronization at zero-degree phase angle difference.
3

Automatic Frequency & Voltage Regulation for Synchronization

When frequency difference does not meet synchronization requirements, the controller automatically regulates the frequency and voltage of distributed power sources to quickly and smoothly enter the preset synchronization range.
4

Three Islanding Modes for Multi‑scenario Application

Supports three islanding modes: scheduled islanding, emergency islanding, and unplanned islanding, covering remote dispatch, local operation, and automatic triggering scenarios.
5

High‑reliability Industrial‑grade Hardware Design

Silicone panel buttons + rubber sealing waterproof design (IP55) + industrial-grade or military-grade integrated circuits + embedded real-time operating system, providing high reliability industrial design.
6

Multi‑interface Support, B‑code Time Sync & Four‑remote Functions

Supports CAN BUS, Ethernet, RS485, and B-code time synchronization. It can connect with EMS to realize remote signaling, telemetry, remote control, and remote adjustment functions.
7

Power‑loss Resistant Waveform & Curve Recording

Complete event waveform recording and power curve recording are retained after power loss. Breaker opening/closing operation waveforms can be reviewed, including voltage, frequency, and phase angle information.
