In conference EPE 2011 was presented the monitoring system to measure and visualize the performance parameters of the hybrid power system. Now we would like to present data analysis results computed by developed application. The application reads the measurement data (it has been acquired for last nine months) from the monitoring system. This data is transformed to power flows in the individual branches, equipment’s power factors and performance parameters in the graphs. The application is currently used for hybrid power system review. The paper describes achieved results and needs for further improvements of such solution.

This paper describes a tester for automated testing of power quality analyzers, focuses on evaluation of correct gapless and non-overlapping measurement according to standard IEC 62586-2[1]. A test is used in order to verify the accuracy of the basic time window for evaluating RMS voltage values (10/12 cycle), and to evaluate whether during the measurements RMS samples (gapless) are not lost and mutual overlaps of individual cycles are not produced. The tester is based on principles of virtual instrumentation. The testing hardware uses PXI system architecture and the software is made in NI LabVIEW programming environment.

Nowadays the smart management of buildings is increasingly frequent and more desirable. The article focuses on one part of the intelligent management of buildings, the control of light. Measurement system was created for measuring light intensity and is used to experimentally verify and evaluate efficiency of controlled lighting in the room. This is based on virtual instrumentation and use of USB measuring card NI 6009.

The article describes the application for synchrophasors monitoring from Phasor Measurement Units (PMU) and Phasor Data Concentrators (PDC). The application is designed for user-friendly visualization of synchrophasors from PMU and PDC. The application meets the requirements of IEEE Std C37.118-2005, which represents the standard in this field.

The National Instruments CompactRIO is an advanced embedded control and data acquisition system designed for applications that require high performance and reliability. This modular system has many new features like open embedded architecture, small size, small power consumption, extreme ruggedness, and flexibility. CompactRIO combines an embedded real-time processor, a high-performance FPGA, and hot-swappable I/O modules. Each I/O module is connected directly to the FPGA, providing low-level customization of timing and I/O signal processing. Full functionality of modular power quality analyzer formerly developed for PCbased instrument has been transferred to CompactRIO platform. This solution represents new level of technology for very flexible, powerful and robust power quality monitoring systems. In comparison with PC-based Power Quality Analyzer brings CompactRIO smaller size, lower power consumption and wide temperature range. Together with SW redesign needed because of HW platform change was developed new user interface concept with many revolutionary features.

The Power Quality Analyzer based on PC technology fully uses the advantages of virtual instrumentation approach. Its functionality is based on requirements of the latest power quality standards e.g. IEC 61000-4-30, 61000-4-7, 61000-4-15, EN 50160. The performance of today's PCs allows comprehensive view to numerous of measured parameters. This solution provides easy access to all common PC connectivity interfaces (HW&SW), data sharing and easy manipulation including the powerful data post processing.

The Power Quality Monitoring becomes more and more important because of the liberalisation of the energy markets. Electrical energy becomes product and customers want quality product for their money. There are a lot of international (European) and national standars connected with power quality. IEC 61000-4-30 very precisely defines how should be required power quality parameters evaluated and also defines measurement uncertainlity for each parameter. In IEC 61000-4-30 are defined two classes of instruments: class A and class B. This article provides analysis of some metrological aspects of power quality analyser.
