2015-11-09 Ukraine: Active Power Line Conditioner in Uninterruptible Power Supply System


Active Power Line Conditioner in Uninterruptible Power Supply System

Description of the project offered: 
Today quite a significant problem in energetics and power electronics is networks electricity quality deterioration that is displayed in power factor decreasing and increasing of higher harmonics in consumption current that results in mains voltage distortion, which is unacceptable if loads requiring high power quality are connected to the same network. The above listed negative effects lead to energy losses in network and equipment which in turn is one of the reasons for auxiliary heating and resource reducing of devices that require high quality power. Another problem is ensuring uninterruptible equipment power supply. The consequences of intermittent power supply can be: data loss, devices resource reducing or even their disabling. 

The project seeks to develop the hybrid device that solves all the above listed issues – reactive power compensators that can operate as uninterruptible power supply (UPS). With THD of tens percent the most appropriate is to use active compensators as active power line conditioners (APLC). The project will focus on designing the reactive power compensator control system based on microprocessors and creation of an effective operation algorithm. The main problem in control task of such a device is the compensator operating modes constant change, which is described by complex and cumbersome expressions of energy processes. This leads to the fact that the microprocessor has to perform a large number of transactions, which limits the entire control system performance.

For battery efficient use it is necessary to ensure charge control, self-discharge current compensation and connection number minimization that prolongs its operation. One of the variants of such battery use as a part of UPS based on APLC is its charge with asymetric current. It will also have a positive impact on temperature operation mode of the battery.

Based on the method of the current and voltage mean values as well as taking into account the energy balance the calculation algorithm of basic parameters and control laws of active power line conditioner with direct current battery charge should be developed to determine the interrelation between the device operating intervals, storage elements parameters, sinusoidal current amplitude and laws of pulse duty factors variation at corresponding intervals.
