SINAPE was developed in cooperation with the main electric power utilities in Brazil and aims to meet the needs of analysis, classification and documentation of the fault recordings. Its goal is to increase the productivity of the analysis process by forming a unique platform for disturbance studies and facilitating the exchange of information between utilities. The program, which runs on Windows © platform, is part of a research line aimed at finding integrated solutions for perturbation analysis.
SINAPE allows for manipulating records of multiple files, avoiding the need to use different programs with different interfaces and operational functions. The program adopts the COMTRADE standard of IEEE (binary and ASCII) and allows the integration of translators of proprietary formats.
SINAPE consists of several modules that implement functions ranging from simple visualization of analog and digital waveforms, through algorithms of phasor analysis and fault location, to the possibility of merging information from one or more files.
SINAPE'S MAIN FEATURES
SINAPE aids the visualization and treatment of the fault recording files by the fault analyst. It has the following characteristics:
• Plotting of fault recording channels: Analog signals are represented in their waveform over time, with instantaneous or effective amplitude values (RMS), and a low-pass or high-pass version of the signal can also be represented. It is possible to expand the signal in time and in amplitude with "zoom" memory, to activate interpolation (linear, polynomial or digital filtering), as well as to scale channels or set of channels by the maximum amplitude automatically. The presentation of the colors and position of the analog and digital signals can be done manually or using pre-selected criteria (digital channels with activity, grouping of channels on the same axis, etc.).
• Quantity measurements: absolute amplitude and RMS values, absolute time and time relative to trigger which can be measured in seconds or degrees, as well as the difference between two values.
• Creation of virtual fault recordings: SINAPE has resources for creating a new oscillogram from one or more real files. In this way, it is easy to compare events recorded by different equipment. This feature comes with functions for changing sampling rates and tools for the synchronization of channels from different registers.
• File reading and generation: easily reading files in any directory computer, with date / time filter, including time zones, installation and logger. SINAPE works with compressed or uncompressed COMTRADE files, and it is also possible to translate files from some formats to COMTRADE. The program also allows saving new files generated from the changes in the originals.
• Other facilities for the user: insertion of comments on the chart, representation of escalated quantities for primary or secondary values, use of pre-programmed masks to define items such as order, color and channel grouping, export in graphic form (figures) or (tables) for text editing applications or spreadsheets, in addition to printing the plot window. It is also possible to simultaneously view one or more recordings and access the contextual help system with hypertext.
Contains analysis tools that allow for generic operations on curves (sum, subtraction, product, power, RMS value, module value and fundamental component angle, scaling, exponentiation and other programmable functions) to more specific functions like calculation of fault impedance, fault location on transmission lines (using information from one or two terminals) and harmonics calculation.
SINAPE tools are prepared to work with any sampling rate, even if not multiple of the fundamental system frequency. These applications have a graphical interface that allows analyzing the evolution of calculated values over time, as are the cases of phasor, harmonic and impedance analysis.
