The results of our integrated solutions provided over the years are reflected in our know-how of the main and most diverse offers of the electrical quality market. Additionally, our strong relations with reliable suppliers allow us to advice our clients and meet their software and hardware needs.
Nowadays, it is vital to have an integrated measurement, control and protection system. The variety of protocols, such as DNP3, IEC870, Modbus and the new standards IEC61850 Goose and MMS, demand a correct use of the data as well as the use of the most convenient hardware to achieve satisfactory results. The availability of precise and synchronized data, its storage, treatment and presentation, must allow users to be able to access this data at all times and in the most appropriate format. The reliability, ruggedness and versatility of a well-created historical database will allow for a correct elaboration of fault reports and the supply of data to carry out engineering projects. And these will later shape the decisions taken by the management, the evaluation of companies’ assets and losses, etc.
The replacement of the previous measurement technology with the new smart communication equipment gives us the possibility to have any electric variable in different devices simultaneously, without transfer troubles or electric signal repetition in the equipment.
By means of the use of data concentrators, it is possible to design data management strategies effectively and avoid the loss of data due to temporary communication faults between auxiliary supply devices. Furthermore, with the simultaneous use of the same hardware, such as communication gateway, it is possible to apply protocols to implement strategies to use data efficiently among different IEDs for monitoring, control, operation interlock, etc.
We provide solutions for data use and data exchange interfaces between software modules that carry out specific tasks, such as statistical analysis, relational database storage, data treatment for maintenance systems, data supply for marketing purposes, etc.
Real-time data handling has certain requirements in the communication interfaces of the devices, not only in what’s related to the hardware and software for the correct data flow, but also in the diagnosis of the system’s integrity. This type of data is characterized by the high dependency of availability, the need for time-based synchronism and the use of wireless and fiber-optic communication channels with Ethernet networks ruled by protocols or virtual networks for different purposes as advised by IEC61850. It is crucial for telemetering and remote control data handling to have systems designed for the maximum use of the communication channel and with powerful diagnose and alarm functions in order to assure data handling in critical moments.
La utilización sincrofasores consiste en el uso de valores digitales y analógicos asociados a una estampa de tiempo muy precisa. Con este último factor los datos adquiridos desde diferentes localizaciones y perfectamente alineados con precisión del milisegundo, son procesados en forma coherente y pueden ser utilizados en exigentes aplicaciones de control y visualización en tiempo real para anticipar eventos así como en análisis post-falla. Con las características de sincronización cumplimentadas, pueden implementarse complejas estrategias de protección de área amplia tales como detección y corrección de estabilidad de tensión, despeje de carga o generación excedentes, formación de sistemas con funcionamiento en modo “isla”, control de fuentes de generación intermitentes y su interconexión a la red, etc.
The use of synchrophasors consists of analog and digital values with an associated precise time stamp. With precise time, data collected from various locations and time-aligned (with millisecond-level accuracy) are then processed as a coherent data set that can be used for real-time control and visualization applications, to predict events, and for post-event analysis. These synchronization characteristics allow us to implement complex wide-area protection strategies such as voltage stability detection and correction, load/generator shedding, islanding control, intermittent generation source control and grid interconnection, etc.
We can provide dedicated communication networks—with wireless or fiber-optic technology—for real-time data transmission both for acquisition and monitoring tasks, and for more complex functions, such as control and protection, as supported by standard IEC61850, with high-priority virtual networks, etc.
