Praxis 98.6.034.704 PMS Module Mega Guard is an advanced Power Management System (PMS) module developed by the renowned Dutch company Praxis Automation Technology. With profound technical accumulation over the past more than 50 years, the company has been dedicated to designing and manufacturing automation, navigation, and electric propulsion systems for commercial ships, super yachts, and naval vessels, among others. As a key component in its product line, the Mega Guard PMS module provides reliable guarantee for the comprehensive automation of ship power systems.
Functional Features
Comprehensive Power Management: This module enables full automated management of the ship's power plant, covering core functions such as power distribution, diesel engine control, generator control, synchronization operations, and generator protection. Through precise algorithms and efficient control logic, it ensures that the power system operates stably and efficiently under different working conditions of the ship, rationally allocating power resources and avoiding power overload or waste.
Independent and Reliable Operation: Each generator set is equipped with an independent and autonomous PMS system. This design greatly improves the reliability and availability of the system. Even if some systems fail, the PMS of other generator sets can still work normally, ensuring the power supply for key ship equipment and reducing navigation risks caused by power failures.
Intuitive Information Display: The module is equipped with a graphic display that can clearly present key power parameters such as circuit breaker status (on/off), generator power, voltage, current, power factor, bus voltage, and frequency. Crew members can quickly obtain the real-time operating status of the power system through the concise and clear interface, facilitating timely decision-making and adjustments.
Convenient Configuration and Operation: The standard Mega Guard PMS is easy to configure during installation. The graphic display provides a user-friendly menu-driven interface, allowing operators to easily input parameters such as generator power, number of generators, bus tie circuit breaker position, nominal bus voltage, alarm limits, and diesel/shaft/shore power generators. This significantly shortens the installation and commissioning time and improves work efficiency.
System Scalability
The Mega Guard PMS has excellent scalability, and functional modules can be flexibly added according to the actual needs of the ship:
Diesel Engine Safety System: It can monitor the operating status of diesel engines in real-time, such as key parameters like oil temperature, oil pressure, and speed. Once an abnormal situation is detected, it immediately triggers an alarm and takes corresponding protective measures to prevent the engine from being damaged due to faults, extend the engine's service life, and ensure the stable operation of the ship's power system.
Synchronization Checker with Standby Measurement: It performs backup measurements of power (kW), voltage (V), current (A), frequency (Hz), and power factor (cosΦ), ensuring that power parameters can still be accurately obtained when the main measurement channel fails. This guarantees the accuracy and reliability of synchronization operations and avoids generator grid-connection failures or power system instability caused by measurement errors.
Frequency and Voltage Analog Control: Through precise analog control algorithms, it finely adjusts the frequency and voltage of the power system to keep them within specified ranges. This is crucial for ensuring the normal operation of equipment on the ship that has high requirements for power quality, such as communication equipment and precision instruments, and improves the stability and power quality of the power system.
Physical Specifications
Diversified Installation Methods: Two common installation specifications are provided. One is 144x144x55mm (width x height x depth), suitable for embedded panel installation. It can be smoothly installed on the front door of the switchboard without occupying additional space, while facilitating operators' viewing and operation. The other is 127x198x29mm (width x height x depth), used for DIN rail installation, which can be conveniently installed on the DIN rail inside the switchboard, saving space and facilitating wiring and maintenance.
Connection Cable Adaptation: An I/O cable with a length of 3 meters or 5 meters is equipped between the PMS operation panel and the PMS I/O module, which can be flexibly selected according to the actual installation position requirements, ensuring stable and reliable signal transmission and facilitating system integration and installation.
Application Scenarios
Commercial Ships: Widely used in various commercial ships such as cargo ships and passenger ships. During cargo ship transportation, it can intelligently allocate power according to different working conditions such as cargo loading/unloading and navigation status, ensuring the stable operation of ship equipment such as cranes, ventilation systems, and lighting systems, reducing energy consumption, and improving operational efficiency. In passenger ship operations, it provides reliable power support for numerous on-board living facilities, entertainment equipment, and navigation safety equipment, enhancing passenger experience and navigation safety.
Super Yachts: Meets the strict requirements of super yachts for high-end power management and comfort. It can provide stable power for luxury facilities on the yacht, such as central air-conditioning systems, audio-visual entertainment systems, and high-end kitchen appliances. At the same time, it ensures that the power system operates quietly and efficiently, without affecting the luxurious atmosphere and navigation experience of the yacht, demonstrating high-end quality.
Naval Vessels: Plays a key role in the complex combat and navigation environments of naval vessels. It ensures the stable power supply for weapon systems, communication systems, radar systems, and various shipborne equipment on the vessel. Even under harsh sea conditions and high-intensity combat conditions, it can ensure the reliable operation of the power system, providing a solid guarantee for the combat effectiveness and survivability of the vessel.
