Training of an artificial neural network in the diagnostic system of a technical object

Creating of structure of facts for the knowledge base of an expert system for wind power plant's equipment diagnosis

“…The paper by (Duer 2010 [4,14,[20][21][22][23][24][25], makes the use more specific (and improved) of the results of diagnostic testing in the organization of a technical object's maintenance system. The paper presents the mechanism of a negative change of states in a technical object, as a result of which there occurs in the object a reduction of its operational properties: a change of the state.…”

“…Onshore (WPPs) are usually characterized by irregular localization of particular Wind Turbine Generators (WTGs) due to topographical conditions [4,20,24] (Fig. 1).…”

“…The (WPP) was designed to be located in the north of Poland, that is to say, in the 1 st grade wind energy zone in Poland. The (HV) Substation was designed as power output into the grid [11,[20][21][22][23]. The Wind Farm Substation is connected into the Grid Operator's Substation at the (PCC) by means of a (HV) cable power line.…”

“…2). To make diagnostic evaluation of the technical object, it requires possessing diagnostic and engineering knowledge on construction, operation, and diagnosis of such technical objects [11,[20][21][22][23] This section presents information by its stages due to a multilevel way of transformation of information on the object into a form of an expert knowledge. Stage 1 is a presentation of a fundamental theory relating to functioning and operation of (WTG) and (WPP's) equipment.…”

An innovative hybrid insulation switch to enable/disable electrical loads without overvoltages

“…Moreover, the generation of the electric arc on the connector contacts adversely affects the operation of the other devices in the vicinity of the switch [11]. Frequent commutation causes harmonics in the power supply circuit of other technical receivers [12].…”
