Problems solved by technology

[0005] However, the existing primary frequency modulation monitoring boards of the power grid all use foreign processors, and the core technology has been closed for a long time. We cannot grasp the core principles. Coupled with the uncertainty of the external environment, the product has serious uncontrollable problems and is easily affected by the external environment. As a result, the product is discontinued, and when it is more serious, it is easy to be stolen by the back door reserved by foreign manufacturers, resulting in the inability to guarantee the data security of the product and fail to meet the security requirements of the power grid system

Abstract

The invention provides a power grid primary frequency modulation monitoring mainboard based on a Loongson platform. The power grid primary frequency modulation monitoring mainboard based on the Loongson platform comprises a substrate, and a Loongson SOC, a power supply access module, a state monitoring module and a PSU power supply module which are arranged on the substrate, wherein the power supply access module, the state monitoring module and the PSU power supply module are electrically connected with the Loongson SOC, and the state monitoring module and the PSU power supply module are electrically connected with the power supply access module; the power supply access module comprises a plurality of relays used for receiving power supply voltage of a power grid; the state monitoring module comprises a plurality of state indicating lamps used for indicating the working state of the mainboard, and the Loongson SOC is adopted as a main control chip, so that the data acquisition, data processing analysis and communication performance of the power grid primary frequency modulation monitoring mainboard can be improved, and the autonomous controllability and safety of the power grid primary frequency modulation monitoring mainboard are improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a primary frequency modulation monitoring mainboard of a power grid based on a Godson platform. Background technique [0002] With the increasing proportion of large-capacity units in the power grid and the improvement of users' requirements for power quality, the frequency stability of the power grid is becoming more and more important. The fault tripping of large-capacity units will have a huge impact on the frequency of the power grid, and the hysteresis of the power grid dispatching system and automatic generation control adjustment will not be able to meet the requirements of stable operation of the power grid. The effective investment of the primary frequency regulation function of the grid-connected unit can fully make up for this deficiency. [0003] Primary frequency modulation (Primary Frequency Modulation / Primary Frequency Regulation, PFR) refers to the inherent abi...
