Embodiment 1
[0056] The broadband multi-frequency electrical quantity unified measurement and analysis system includes at least one front-end electrical quantity measurement device arranged at the substation bay layer, and a data storage and analysis host computer arranged at the inter-station coordination control layer. The front-end electrical quantity measurement device is cascaded The switches and data storage and analysis hosts perform data transmission. The front-end electrical quantity measurement device can collect various low-frequency, power-frequency and high-frequency signals in the steady state, dynamic and transient state of the power grid at high frequency and perform calculation, analysis and transmission; the back-end measurement data storage and analysis host can receive front-end measurement The data transmitted by the device is stored, and at the same time, the received data can be analyzed and displayed; the upload of received data, the transmission of data analysis res...
Embodiment 2
[0087] The present invention also provides a method for implementing a unified measurement and analysis system for broadband multi-frequency electrical quantities, including:
[0088] The electrical quantity measuring device collects grid data at high frequency;
[0089] The data storage and analysis host receives and stores the grid data transmitted by the electrical quantity measuring device, and at the same time analyzes, displays and forwards the received grid data, and transmits the data analysis results.
[0090]Further: the grid data is stored, including: when there is one electrical quantity measurement device, the data storage and analysis host stores according to different devices, different ports and different types; when there are two or more electrical quantity measurement devices When installed, the data storage and information interaction of multiple electrical quantity measurement devices in the substation are carried out through the networking module;
