Technical Field

The invention relates to the technical field of automatic monitoring, in particular to a remote monitoring system for a new energy power station.

Background

In recent years, renewable energy power generation technologies represented by wind energy and solar energy have been rapidly developed in the world. However, with the continuous expansion of the application range, the problems of randomness and volatility of the renewable energy power generation become prominent gradually, and the large-scale application of the renewable energy power generation technology is seriously influenced. Meanwhile, with the continuous development of social economy, the power demand is rapidly increased, and the requirements on safety and diversity are higher and higher, which provide high requirements for the economic and safe operation of a power grid.

In order to ensure the safety and reliability of the power transmission system, various indexes of the transformer substation need to be effectively monitored in real time. At present, most substations in China adopt an off-line monitoring method, a power company needs special workers to overhaul substation equipment regularly, the workload is high, the labor cost is high, in addition, power failure work is needed for each overhaul, the power supply reliability is influenced, loss and inconvenience are brought to production and life of people, and the risk is possibly brought to the safety of a power grid due to the power failure work. With the rapid advance of the intelligent construction of the domestic transformer substation, some on-line monitoring systems are developed in some transformer substations, but all the on-line monitoring systems are local single monitoring systems based on a wired communication mode and only can monitor a certain data of the local transformer substation. Due to the heterogeneous distributed characteristics of the transformer substations, the existing transformer substation monitoring system is various in types, low in intelligent degree, poor in internal scheduling coordination of the monitoring system and poor in data sharing performance among different transformer substations.
