Convertor station electrical equipment status integrated online monitoring system

The invention discloses a convertor station electrical equipment status integrated online monitoring system which is divided into an advanced application layer, a spacing layer and an in-situ process layer. The advanced application layer is an integrated online monitoring platform. The spacing layer comprises a plurality of electrical equipment status online monitoring intelligent electric devices (IED). The in-situ process layer comprises a plurality of electrical equipment monitoring sensing units. The electrical equipment monitoring sensing units carry out information exchange with the electrical equipment status online monitoring IEDs through cables or optical fiber. The integrated online monitoring platform accesses data of the online monitoring IEDs of the spacing layer through adoption of an Ethernet switch. The online monitoring IEDs are used for building models based on an international electrotechnical commission (IEC) 61850 standard, and building a structure provided with a full convertor station integrated online monitoring database and an integrated online monitoring analysis and diagnosis function. The convertor station electrical equipment status integrated online monitoring system accesses the integrated online monitoring platform through the adoption of a unified regulation and a communication interface, eliminates background devices of online monitoring IED systems of various manufacturers, simplifies configuration of the devices, and reduces construction cost.
