采用PMU频率信息进行发电机组一次调频的装置
摘要：
本实用新型公开了一种采用PMU频率信息进行发电机组一次调频的装置，包括PMU装置,还包括频率数据抓取发送装置，所述的频率数据抓取发送装置用于对PMU装置的频率数据进行解析并发送至发电机组的DCS或DEH，使发电机组根据所述接收到的频率数据进行一次调频，所述的频率数据抓取发送装置的输入端连接PMU装置或者PMU装置与调度中心间的通信网络，所述的频率数据抓取发送装置的输出端连接发电机组的DCS或DEH。本实用新型利用PMU装置检测的频率数据，通过频率数据抓取发送装置对PMU装置进行所需频率数据的抓取，并把频率数据发送到发电机组的DCS或DEH，发电机组的DCS或DEH以此数据为一次调频标准，从而使一次调频更加精准。
摘要（英）：

The utility model discloses a device for performing primary frequency modulation of a generator set by use of PMU frequency information, which comprises a PMU device and a frequency data capturing and sending device, wherein the frequency data capturing and sending device is used for analyzing the frequency data of the PMU device and sending the frequency data to the DCS or DEH of the generator set, so that the generator set performs primary frequency modulation according to the received frequency data; an input end of the frequency data capturing and sending device is connected with the PMU device or a communication network between the PMU device and a scheduling center; and an output end of the frequency data capturing and sending device is connected with the DCS or DEH of the generator set. According to the device disclosed by the utility model, the frequency data capturing and sending device captures the required frequency data for the PMU device by use of the frequency data detected by the PMU device, and sends the frequency data to the DCS or DEH of the generator set; and the DCS or DEH of the generator set takes the data as a standard of primary frequency modulation, so that the primary frequency modulation is more accurate.
