The interface presented in this paper performs a synchronized sampling of all eight common-mode or differential analog inputs with a high sampling rate. This is a low cost interface, entirely controlled by the PC104 CPU. The paper is focused on design and operation aspects of the synchronized analog-to-digital conversion module. This interface is recommended for high speed data acquisition systems and finds its utility in energetic systems, for monitoring the power quality and for recording different specific transient events. Some programmable electronic modules which perform analog and digital signal acquisition in energetic systems already contain a PC104 interface with synchronized sampling of analog inputs; some experimental results are also presented in this paper.

“…The block diagram of the PC104 interface with synchronized sampling of analog inputs is presented in Fig. 1 and the detailed hardware architecture is presented in [4].…”

Many programmable electronic modules for data acquisition and processing can be found in power systems. To monitor and record different specific high speed transient events in energetic systems, an adequate data acquisition and processing method is required. This paper deals with such method and its application in data acquisition for implementation of complex protection functions. The acquisition routine for analog and digital channels, detailed acquisition and storing process for analog and digital values, storing and calculation method for acquired digital and analog values are all presented. The proposed method is adequate for many and various practical applications which require high speed data acquisition systems.

“…Causes of disturbances in power systems, power quality improvement techniques and measures used to estimate the power quality are presented in [1] and [2]. Many methods and types of equipment for power quality measurement, monitoring, analysis and diagnosis of electrical events in power systems were designed and implemented in the last years; some of them are presented in [3], [4], [5], [6], [7], [8], [9] and [10]. This paper is focused on the PC-08/104 equipment for monitoring and analysis of transient electrical events.…”

Many power quality problems are generated by various electrical events (faults, disturbances, etc.). This paper presents the PC-08/104 equipment for monitoring and analysis of transient electrical events in power systems. It is a programmable electronic module which runs according to the signals provided by the transducers that take over the process parameters. PC-08/104 performs the acquisition of analog and digital inputs, local data storage, monitoring and processing, data transfer to an IBM-PC compatible computer and communication with the process server in a distributed data acquisition system. The program which runs on an IBM-PC compatible computer contains three sections: Monitoring (configuring all settable parameters of the equipment), Analysis (visualization of the input signals waveforms and the computation of several characteristic values) and Manager (management of records and archives). PC-08/104 provides an excellent tool to analyse the performance of the power system before, during and after a network disturbance situation. Some experimental results obtained using this equipment in energetic system are also presented in the paper.
