GCS Generator Synchronization Panel

Material: carbon steel
Color: Gray
Place of Origin: Shanxi, China
Application: Industrial
Product Category: Power Distribution Equipment

This product is a derivative of the GCS‑type low‑voltage draw‑out switchgear, specially designed for parallel operation of diesel generators. Suitable for AC 400 V three‑phase four‑wire low‑voltage distribution systems, it enables synchronous paralleling, load sharing and intelligent control for multiple diesel generators. It features automatic synchronisation, active/reactive power sharing, fault protection and remote monitoring. Adopting a draw‑out modular design for convenient maintenance, it meets the operational requirements of multiple‑generator parallel systems and delivers stable, reliable redundant power for heavy‑duty loads.

① GCS‑type draw‑out modular construction simplifies maintenance. Faulty units can be replaced rapidly to minimise system downtime.

② High‑precision automatic synchronisation achieves shock‑free paralleling, eliminating inrush‑current impact during synchronisation and protecting both generators and connected loads.

③ Intelligent load sharing automatically distributes active and reactive loads according to each generator’s rated capacity. It facilitates economical operation of multiple generator sets and extends equipment service life.

④ Comprehensive protection suite includes reverse‑power, over‑voltage, under‑voltage, over‑frequency, under‑frequency, short‑circuit and overload protection. Automatic alarm and tripping are triggered under abnormal conditions to safeguard generators and the whole power system.

⑤ Multi‑generator parallel capability supports up to 32 operating units. It satisfies redundant power‑supply demands for high‑load facilities such as large‑scale data centres, power plants and heavy‑industry factories.

Q1: What is the function of a generator paralleling panel?
A: A generator paralleling panel enables synchronous parallel operation of multiple diesel generators. It combines power outputs from multiple generators onto a common busbar to supply loads collectively, while performing automatic load sharing, fault protection and remote monitoring to ensure stable and reliable power delivery.

Q2: What is the maximum number of generators that can run in parallel?
A: The standard version supports up to 32 paralleled diesel generators. Systems for larger quantities can be custom‑built upon request.

Q3: Does it support automatic synchronised connection?
A: Automatic synchronisation comes as standard. It realises automatic synchronisation, paralleling and load distribution without manual intervention, enabling unattended operation.
