Regardless of the originating source of energy, electricity is the primary sort of power to be employed. Each renewable energy source, such as wind, solar, hydrogen, waste to energy, and so on, Power Supply systems are critical for power plants because they provide a stable source of electricity when the grid fails. A UPS system protects the power plant from unexpected power interruptions and ensures the facility’s efficient and safe functioning. A UPS system also serves as a backup power supply for important power plant components such as control and safety systems. This contributes to the power plant’s continued safe and efficient operation, especially during power interruptions. Lastly, a UPS system helps to decrease maintenance expenses by delivering consistent, uninterrupted power also instruments are an important component of a power plant because they provide reliable and fast data that can be utilized to monitor, evaluate, and manage the performance. Instruments are an important aspect of a power plant because they provide reliable and timely data that is utilized to monitor, evaluate, and manage the plant’s operation. Instrumentation assesses many characteristics of the plant, such as temperature, pressure, flow, and voltage, and provide data that may be used to make educated decisions about how to improve the plant’s performance. Instruments are also used to detect possible faults and warn operators to prospective problems that need to be addressed. Lastly, instruments are employed to assure the safe running of a power plant by giving data that is utilized to detect any potentially hazardous circumstances.
Products and Solutions
UNINTERRUPTIBLE POWER SUPPLY (UPS SYSTEMS)
applications for UPS systems. MGEC provides UPS specifically for applications. The systems, which have an all-aluminum casing, have been tested for shock and vibration and are available in power ranges.
The Uninterruptible Power Supply is customized according to the customers’ requests.
ONLINE UPS SYSTEM
In online operation the systems of the guarantee the optimal supply of all connected consumer loads as a stable output voltage is ensured permanently free of all standard interference pulses, overlapping currents and fluctuations. Thus, critical consumers are always provided with secure voltage.
INNOVATIVE TECHNOLOGY
Using a modern IGBT rectifier reduces disturbances in the mains supply significantly. The innovative IGBT rectifier provides for an almost sinusoidal current consumption. Thanks to the improved performance factor at the input to the rectifier the UPS systems of these types have a reduced input performance by up to 30% in comparison to common UPS systems with a Thyristor rectifier. The reduction of current at the input to the rectifier during grid feed enables a considerable saving when dimensioning the distribution of fuses and cables on-site.
DC/AC CONVERTERS (INVERTERS)
Inverters are extremely suitable for power supply of critical consumers with single-phase or three-phase connection. The robust inverters are especially used in communication facilities, but also for special applications and under extreme environmental conditions, e.g. on off- shore platforms.
INVERTERS AS EMERGENCY POWER SUPPLY
The power supply of the inverter is ensured via 110 V or 220 V battery. The power supply is also possible via rectifier. The consumers can be supplied optionally by DC source primarily or by bypass- supply. The priority grid is freely selectable by customer
PULSE WIDTH MODULATED IGBT INVERTER
A pulse width modulated IGBT inverter, a static as well as manual bypass and a self-diagnosis system are significant parts of our system. All for the functioning important messages are clearly visualized on the front door via LCD display. The static bypass ensures automatic change to the grid in the event of an inverter failure or overload. During maintenance or repair the device can be bridged via manual bypass in order to continue the supply of the consumers. The transfer to manual or static bypass and back is ensured by rapid switching thyristors; an isolation transformer is located in the output of the inverter. The integrated self-diagnosis system guarantees high reliability and easy servicing. Via special (optional) software it is possible to execute a remote diagnosis, if needed.
COMFORTABLE OPERATION
The operating panel of the HPI systems allow simple operation. The menu-driven program guides smoothly to all display and operation functions of the system. Via a comfortable text display all measurement values, alerts and status messages are indicated. LED displays ensure that the status of the inverter can be assessed at a glance.
RESISTORS and LOAD BANKS
MGEC designs resistors and load banks for a various wide range of technical application and with ratings up to several megawatts.
- PORTABLE LOAD BANK – THE TEST RESISTOR UP TO 30 KW FOR FLEXIBLE SERVICE ASSIGNMENTS The easy to transport load banks of these series are available with an output up to 30 kW and ideally suited for flexible service assignments. Depending on the type they can be used to test voltage values up to 3×400 VAC or 690 VDC. We also provide voltage pick-ups with those systems and further optional equipment. Due to its low net weight, easy operation and transportation facility, this model is a must for any service technician carrying out stress tests. The housing with IP 20 protection class is made of stainless steel and all versions have handlebars and supporting feet.
- SMALL MOBILE LOAD BANKS – SMART UP TO 250 KW The load banks series are compact and easy to dismantle into 3 components in just a few simple steps. While the large types of EASY XL (output range 150/200/250 kW) require a van for transport, the resistors of the type EASY (output range 50/75/100 kW) just need a passenger vehicle for easy transport. Depending on the version these load resistors can be used for up to 3×400 VAC or 920 VDC. The installation and connection of this series are done quickly and only need a few steps. A stable transport frame with lockable swivel castors enables flexible use in direct proximity of the test sample. All load levels of our load banks are secured and will be switched off in case of a fan fault. We gladly finish customized colors or print your company name.
- Testing resistors – Move up to 1000 KW The load banks of this series are of modularly constructed and designed for an output from 100 kW up to 1000 kW. The individual load levels are installed as plug-in units into a resistance tunnel. Load banks of this type can be adjusted with a control box to a precision of 1kW. This control box can easily be manufactured as remote control with a cable length of 100 m. The load increments have a very low temperature coefficient thanks to the use of special stainless steel, which allows the chosen load to remain nearly constant even in case of warming of the resistor elements. A special design and the arrangement of elements enable a low air outlet temperature also in case of full load selection. The housing of the load bank can be provided either, as permanent fixed position or as mobile version on reels.
