This product is dedicated paralleling‑control equipment specially designed for parallel operation of diesel generators. Suitable for AC 400 V three‑phase four‑wire low‑voltage distribution systems, it performs synchronous grid‑connection, intelligent load sharing, operational control and fault protection for multiple diesel generators. Built on a modular framework, it integrates core components including synchroniser, speed‑governing unit, excitation controller and protection devices. Both automatic and manual paralleling modes are available. Compatible with diesel generators of various brands and power ratings, it delivers stable and reliable redundant AC power for heavy‑duty loads.

① Broad compatibility. It works with diesel generators of diverse brands and power capacities. Parallel operation can be achieved without modifying the generator hardware.

② High‑precision synchronisation control. Adopting a digital synchroniser, it enables shock‑free generator paralleling. Voltage difference, frequency difference and phase‑angle difference during synchronisation are kept within narrow tolerances to protect generators and grid‑connected equipment.

③ Intelligent load management. The system automatically adjusts the number of active generator sets according to actual load demand. It optimises economic operation, reduces fuel consumption and extends equipment service life.

④ Comprehensive protection coverage. It covers both electrical and non‑electrical generator protection (water temperature, oil pressure, rotational speed, etc.). Automatic alarm and tripping will be triggered upon abnormal conditions to secure generator assets.

⑤ Remote‑operation capability. Generator operating status can be monitored via PC or mobile‑phone APP. Remote start‑stop, paralleling and load adjustment are supported to realise unattended operation and maintenance.

Q1: What is the function of a diesel‑generator paralleling panel?
A: A diesel‑generator paralleling panel is specialised hardware for synchronous parallel‑operation of multiple diesel generators. It combines power outputs from multiple generators onto a common busbar to supply loads collectively. It also implements automatic load sharing, operational control, fault protection and remote monitoring to guarantee stable and dependable power supply.

Q2: Can diesel generators from different brands operate in parallel?
A: Yes. This paralleling panel features high compatibility for generators of various brands and power ratings. Parallel operation is feasible as long as the generators are equipped with standard speed‑governing and excitation interfaces.

Q3: What is the maximum number of generators that can be operated in parallel?
A: The standard configuration supports up to 64 paralleled diesel generators. Systems for larger quantities can be custom‑engineered according to project requirements.
