Our offer in automation, control and protection of generation, transmission and distribution systems, includes the manufacturing of basic and detailed engineering, equipment supply and integration and construction services. Our experience allows us to offer our own methodology and uses or adapt our expertise to satisfy our clients’ needs and demands.
By means of high-tech, real-time controllers, we provide systems for distance command from the switch room in LV and MV, with integrated substation alarm system and full communication capacity, with control levels from the remote control center by means of Protocols DNP3, IEC61850, IEC870-101/104, etc.
We develop the engineering and turnkey projects for the re-establishment of frequency and voltage grid stability through especial and wide-area protection schemes by automatic generation disconnection and demand. Our systems allow for the maximum use of the transportation capacity of high-voltage transmission systems or the operation of critical facilities in faulty conditions of the main power supply system through island mode operation.
Through the automation of available supply sources we can provide consumers with the necessary electric power, considering quality and availability. The control of the power supply unit in faulty and normal operation conditions, as well as the possibility of verifying the correct operation of the equipment and backup devices at any time, will allow us to have safe and reliable electric power under any condition. We also provide autonomous and network generating sets, UPS and battery banks, resistive load banks and AC / DC auxiliary services panelboards.
The automatic voltage re-establishment after a temporary fault or the possibility to isolate it, gives us the possibility to minimize the duration of the fault or, in the event of persistent faults, it allows us to protect the affected area. We are thus able to obtain a reduction in the penalty due to supply fault. The maintenance team may also act with an accurate integration with SCADA system.
By means of the registration of special events and alarms, it is possible to quickly diagnose the status of the electrical system, either under normal or faulty conditions. The availability of certain time stamp events is essential in order to study the fault with the necessary performance data. This will allow us to determine the order in which the faults took place and their source.
Although SCADA systems are for general purposes in different kinds of industries and service companies, the management of specific solutions for energy applications by means of the implementation of communication protocols such as DNP3.0, IEC870 or the new standard IEC1850 as well as specific control functions for electric systems, economic load dispatch, energy monitoring, etc., allow us to offer customized solutions with tools that facilitate the development of the applications and the operation of the system.
Nowadays, companies need to have historical and real-time precise data. This translates into the need to have powerful measurement systems, fully integrated with both, software and hardware. Grupo Oeste is highly experienced to develop different applications and is supported by prestigious suppliers that guarantee our daily work. These tools and the careful teamwork permit us to implement the best solution required in each project.
With the results of the pertinent coordination analysis, we can come up with solutions for the protection of networks and machines. Moreover, we provide protection devices with their configuration and tests and integrated solutions: design of panel boards or electrical rooms and power supply auxiliary services.
Our experience in control logic programming for electric system automation and in the application of protocols such as DNP3.0, IEC870-101/104, IEC61850, among others, for CPU or Hot Stand-By Redundancy or Dual Primary Systems, gives us the opportunity to develop solutions of medium and high complexity. Moreover, the constant support of our suppliers of RTUs and PLCs, allows us to offer indispensable consultancy services for the design of conceptual and basic engineering, thus, meeting the highest demands. Our integrated turnkey solutions guarantee the fulfillment of all requirements under any condition. p>
The accurate commutation of the power supply sources allows us to operate the industrial resources reliably, obtaining the availability required by the application. Most of the success has to do with the versatility of the transfer automation and the features of the controllers used.
Today’s trends in the communication world involve a complete integration of control, measurement and protection systems. Thus, it is necessary to have the accurate software and hardware outputs, with wireless Ethernet networks and through fiber optic, in order to facilitate the remote monitoring and configuration of IEDs. There is a strong tendency to replace the traditional copper wired connections with virtual links under new standards such as Protocol IEC61850. It is vital to rely on the communication systems in these conditions and we can provide specific equipment as well as turnkey solutions.
The handling of the flow of power data and having advanced functions to verify the quality of communications or the record of events with the possibility of time synchronization, means that we need to have a hardware with availability, interface variety and communication protocols. We have the accurate equipment, which is manufactured and designed to offer the multi-protocol communication capacity needed to satisfy today’s tendency of standardization and open systems, but with the necessary safety norms required by critical applications.
Many available solutions for automatic regulation for distribution networks and transmission systems allow us today to have the quality of power that the end user needs, which also guarantees the most effective exploitation of the companies’ resources. We provide controls for the automatic or manual handling of controllers, under load of high and low voltage transformers and single-phase and three-phase controllers for transmission lines.
The synchronized entry of transmission lines or generators to the network or to the interconnected electric system uses methods of common use. We can provide equipment to verify the synchronism or solutions either for manual or automatic operations.
We provide protection sets for generator-transformer blocks, detailed engineering of panels, configuration and protective relay tests. Our integrated solutions of IEDs, components of HMI and SCADA systems facilitate the availability of event data and oscillographic records for fault analysis and monitoring from the different supervision levels. The supply of protection systems is usually an integral solution with synchronism and measurement systems.
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 availability of synchronized data of events, alarms and oscillographic records is vital to fault analysis. The recording system has to fulfill the conditions in order to obtain the precise data required by the corresponding standards. The recovery of information has to be fast and easy and demands an accurate integration between hardware and software. We have the tools that permit us to carry out disturbance analysis and record so as to later determine their causes and effects.
