System and method thereof for evaluating real-time running state of wind generating set

Abstract

The invention relates to the technical field of running state monitoring of wind generating sets, in particular to a system and a method for evaluating the running state of a wind generating set. The evaluating system mainly comprises a monitoring module, a quantifying module, a weight confirmation module and an evaluating module; data monitored in real time by a wind generating set control system are utilized as the input of the evaluating system of the real-time running state; then the data are quantified to obtain a real time deterioration degree of each evaluating index; finally, when the deterioration degree of a single item evaluating index and a permissible value have greater deviation, the serious evaluating result is directly given, otherwise, the weight module and the evaluating module are used for calculating an evaluating result of the running state of the generating set, and the evaluating result is used as the output of the system. The invention provides scientific basis for state maintenance of the wind generating set, and provides technological supports for ensuring high-efficient, reliable and safe running of the wind generating set, evaluating and forecasting the operational reliability of an electric power system of a windy electric field, and has important engineering application value.

Description

technical field [0001] The invention relates to the technical field of evaluating the operating state of a wind power generating set, in particular to a system and an evaluating method for evaluating the operating state of a wind generating set. Background technique [0002] With the rapid growth of my country's wind power installed capacity, the proportion of total installed capacity is increasing year by year. With the huge development prospects of resources, the construction of large-capacity wind farms is developing from land to offshore, and even to deep sea areas. Compared with land wind turbines, offshore wind turbines will face harsher operating environmental conditions and higher operation and maintenance costs. For example, the 160MW Horns Rev wind farm in Denmark was built and operated in 2002. In the early stage of operation, there were many faults in the safety system, electronic control system, and transformer of the wind turbines. Only during the operation per...

Problems solved by technology

--For example, the 160MW Horns Rev wind farm built and operated in Denmark in 2002. In the early stage of operation, there were many failures in the safety system, electronic control system, and transformer of the wind turbine. Only during the operation period from 2003 to 2004, The 80 wind turbines are maintained almost twice a day on average, which directly resulted in a loss of nearly 40 million euros in 2004. Such a high field failure maintenance rate and the high maintenance costs brought by it were unexpected by the operator
