System and method for repairing wind generator based on weather information

A method for repairing a wind generator based on weather information, the method using a computer processor for executing operations performed by a plurality of modules, the method comprising:

• receiving operation signals and threshold performance numerical values from the wind generator by a part state diagnosis module, the operation signals representing measured performance numerical values obtained from sensors respectively mounted to each part of the wind generator and the threshold performance numerical values representing a part performance threshold for each part of the wind generator as preset by a user based on an acceptable loss of power generation;
• diagnosing a part state of each part of the wind generator in real-time by determining in the part state diagnosis module whether a currently measured performance numerical value of a specific part of the wind generator exceeds a preset part performance threshold for the specific part of the wind generator, the diagnosing simultaneously including diagnosing a change in a threshold performance numerical value received over a predetermined period and continuously diagnosing the change in the threshold performance numerical value in real time in response to an operating environment of the wind generator;
• transmitting the diagnosed state of each part from the part state diagnosis module to the user and to a repairing type determination module;
• determining, in the repairing type determination module, a required repairing type and a priority of the required repairing type, the required repairing type determined according to the transmitted diagnosed state of each part, the priority of the required repairing type determined by comparing the diagnosed state of each part with a stock condition of a corresponding part and a work state of the user;
• establishing a database by inputting to the database data indicative of each of a repairing type of an instance of repair work performed, a count of repairing personnel of the instance of repair work performed, and weather information incident to the instance of repair work performed, the repairing type categorized according to parts of the wind generator including the specific part of the wind generator;
• analyzing weather information corresponding to the operating environment as determined by at least one weather condition of a wind velocity, a precipitation, a wave height, and temperature by receiving the weather information of an area of the wind generator in real time;
• calculating a repairing duration based on the inputted data of the established database;
• and
• deriving a repairing time for the wind generator by determining a number of weather condition holding days based on the analyzed weather information and the calculated repairing duration,
• wherein the analyzing includes:
• receiving real-time weather information during an instance of repair work being performed in the area of the wind generator;
• extracting, from the received real-time weather information, weather information associated with the instance of repair work among the at least one weather condition, the extracted weather information corresponding to a time period including the repairing time and specifying the weather condition holding days of the time period in which the at least one weather condition has a value less than a weather condition threshold;
• and
• comparing the real-time weather information including an analyzed weather information value (E) with a pre-established workable weather condition including a reparable weather information determination value (C) to transmit a shelter signal to a user based on the comparison, and
• wherein the analyzing further includes:
• interrupting work progress of the instance of repair work being performed in the area of the wind generator, the work progress interrupted in response to the shelter signal;
• calculating a remaining work execution time after the work progress is interrupted;
• comparing a repairing duration of a remaining work load expressed as an remaining work predicted duration (G) with a weather state holding time (H) calculated based on the real-time weather information received after the interrupting;
• and
• completing the remaining work load by restarting the repair work of the instance of repair work, when the remaining work predicted duration is less than the weather state holding time,
• wherein the user returns to the area of the wind generator after waiting a specific time until the extracted weather information indicates the at least one weather condition having the value less than the weather condition threshold.
