The power system protection, control and SCADA industry is undergoing fundamental changes in the way its functions are implemented. Numerical technology is driving together functions that have traditionally been handled as specialist disciplines using separate devices.
Increasingly, protection, metering, control and data communication functions are now all provided in a single device, and customers understandably expect a complete solution to be provided from a single system integrator.
Because Virelec is continuously working with these modern intelligent electronic devices (IED’S) from multiple vendors, we have become very familiar with them in terms of setting, programming and configuring. We frequently find ourselves in the position of being the most knowledgeable specialists on a particular project and are routinely invited to assist in these tasks.
Virelec has extensive experience designing, implementing, and testing Substation Automation Systems. These systems utilize modern protocols (IEC 61850, GOOSE, and DNP3.0) over fibre-optic Ethernet networks, along with IEC 61131-3 based logic to provide fully-automated, high performance, high-reliability Substation Automation Systems.
OEM’s often supply switchgear and power system plant that use third party IED’s specified by their customers and find they lack critical configuration knowledge. Virelec acts as a specialist resource in these cases to configure third party IED’s for either the end customer or the OEM.
Refurbishment projects that involve replacing electro-mechanical relays with modern IED’s result in a daunting array of choices with regard to communications and the integration of data into the utility and corporate operations. Virelec’s engineers are able to assist customers implement the best and most efficient system for data acquisition.
Virelec has long recognized the need to keep current with such technology developments, and has expanded to offer these services to the power industry:
