Abstract

The invention provides a wind power monitoring and fault diagnosis system which comprises a station-control-level computer monitoring network, a bay-level data communication network, a power grid EMS (electronic management system), a data collection system, a transformer substation measuring and control protecting system, a remote working station and units (1...n). The station-control-level computer monitoring network respectively performs data interaction with the power grid EMS, the data collection system and the transformer substation measuring and control protecting system through the bay-level data communication network and controls the remote working station, the data collection system respectively collects data of each collection unit (1...n), and the station-control-level computer monitoring network receives meteorological information of a wind power plant. The wind power monitoring and fault diagnosis system can simultaneously realize functions of monitoring of electrical quantity of wind power and state monitoring and fault diagnosis of a wind power unit, precognition and alarming of fault states of the wind power unit can be realized while wind power monitoring is realized.

Description

technical field [0001] The invention belongs to the field of wind farm monitoring and wind turbine status monitoring and fault diagnosis in new energy power generation technology, and specifically relates to a wind power monitoring and fault diagnosis system. Background technique [0002] Compared with thermal power and nuclear power, wind power has a small single-unit capacity and a large area, and most of them are located in remote areas. The technology and operating conditions are relatively poor. To carry out effective standardized management and improve the efficiency of wind farms, a set of monitoring and management systems with perfect performance is crucial to the operation of wind farms. [0003] Wind turbines are generally equipped with a data acquisition and monitoring (SCADA) system, which can realize basic monitoring of the operation of wind turbines, has functions such as alarming and reporting, and can generate wind farm event reports. Reliability provides st...
