在越来越多的全球业务环境中，GE的数字能源业务为公用事业提供了一个单一的保护和控制设备平台，能够使用其新的通用继电器（UR）固件7.2版满足国际规格和协议。GE的UR为全世界提供了公用事业，以最大程度地提高电气系统保护和控制元素的性能所需的技术。
你的7.2是其先进的通用的最新成员family of protection and control products designed to meet the demanding operating speed requirements of IEC-oriented utilities around the world. Line protection requirements—such as language, special pilot schemes, performance, enhanced selectivity for specific fault cases and communication protocols—for IEC-oriented utilities vary from country to country. While some countries face more stringent standards and regulations than others, GE’s new UR 7.2complies with requirements worldwide and meets the needs of each individual utility.
“The UR 7.2’s advanced technologies, including improvements in line protection functionality, take GE’s protection and control offerings to a new, global level,” said Juan Macias, general manager, GE’s Digital Energy business. “Enhancing our UR line protection to comply with rigorous IEC application requirements enables GE to provide innovative technology capable of meeting and serving IEC utilities’ needs, no matter where they are located.”
As the use of synchrophasor-based applications to monitor electrical grid usage has become increasingly common throughout the industry, it has led to the development of a broad range of phasor measurement unit (PMU) devices. GE’s PMU devices provide comprehensive synchrophasor functionality that addresses the challenges of meeting each region’s specific applications and power system requirements.
其他功能包括：
By generating segregated PMU data for up to six feeders, GE’s UR PMU reduces the number of PMU devices needed for multiple-feeder applications by up to 80 percent. Additionally, up to six VT banks can be connected to a single device.
Devices can simultaneously deliver metering-class and protection-class PMU data, meeting the latest version of IEEE C37.118 (2011) standards and helping to optimize PMU-based metering and protection applications.
New support of PMU data on the UR C60 breaker controller device removes the need for dedicated PMU devices for synchrophasor-based breaker control logic.
The UR 7.2’s PMUs provide comprehensive transformer protection technology, removing the need for dedicated rate of change of frequency devices to be installed to monitor electrical flow spikes.
新的UR还提高了对复杂故障事件的中性定向过电流保护的选择性。
