Embodiment

[0029] Such as figure 1 As shown, the fan data acquisition device in the wind farm sends the fan fault information of the "Anxuneng Fan" in the station in the form of switching value through communication with the fan monitoring, and fills it in the remote information library in the form of remote signaling. At this time, a fault occurs The remote signal is: "YX1=1", which is converted into: "YC1=700" through computer intelligence. It is stipulated that the fan fault information can be concurrently sent up to 5 (N=5). "YX2=1", "YX3=1", "YX4=1", "YX5=1", through computer intelligence into: "YC2=701", "YC3=702", "YC4=703", "YC5 =704", after a period of time, a certain fan fault is eliminated: "YX3=0", the corresponding change of the fault code telemetry library: "YC3=0", and then a fan fault occurs: "YX6=1", due to the earlier telemetry library The "YC3" fault has been eliminated, so at this time: "YC3=705". After a period of time, all fan faults are eliminated: "YX1=0", "YX2=...

Abstract

The invention discloses a unified modeling method based on the state data and fault data of a fan of a wind power plant. The method comprises the following steps of: classifying and aggregating the acquired state data and fault data of the fan; converting the state data or the fault data, which is reported with analog quantity, of the fan into telemetry data, and forwarding the telemetry data to a remote monitoring system; filling the state data or the fault data, which is reported with switching quantity, of the fan into a library in a remote signaling data form; and converting the state data or the fault data of the fan into the telemetry data by using an intelligent conversion method, and forwarding the telemetry data to the remote monitoring system. In the method, a process of converting the switching quantity into the analog quantity for the type of a state code or a fault code of a single fan is provided; concurrent faults of the fault code of the fan in the same time are reasonably and effectively processed; and the operating state and fault state of the fan can be timely and accurately reported, so the data, of different types, of the fan can be subjected to unified analysis, statistics and management through remote monitoring, the accuracy of fault diagnosis of the remote monitoring system of the fan is improved, the working intensity of a monitoring person is reduced, and working efficiency is improved.

Description

technical field [0001] The invention relates to a simple and effective method for converting fan status and fault information data in different data formats from different manufacturers into a unified data format, which belongs to the technical field of power system data processing. Background technique [0002] With the continuous development of clean energy technology, the coverage of wind power plants in coastal and inland areas with developed wind resources is expanding, and the number of wind farms is also increasing rapidly. The manufacturers of wind turbines used by each wind farm are different, and even the same wind farm The fan manufacturers used in different places are also different. Due to the large area occupied by wind power plants and the large geographical span between wind farms, a wind power remote monitoring system that aggregates the fan operation data of each wind farm into the same place for analysis, processing, and display has emerged as the times re...
