Problems solved by technology

[0003] In order to meet the operation requirements of substation ice melting and reactive power compensation, the intensive ice melting device needs to upload or receive a large amount of analog and switch information with the substation and dispatch control center. The existing ice melting device cannot realize reactive power compensation or regional voltage control. , and the substation monitoring background information interaction system used in the intensive DC deicing device has the following problems: Problem 1, cannot communicate with the dispatching control center: In order to achieve grid voltage stability, the AVC system has gradually been widely used in the power grid, and the intensive deicing As a dynamic reactive power source, the device needs to be compatible with the AVC system, so it needs to have communication capabilities with the dispatch control center
Problem 2, it is impossible to send analog signals: In order to realize regional voltage control, the intensive ice-melting device needs to collect analog information such as voltage and current of all lines in the substation
Question 3. The communication requirements for the ice melting device are very high: different components of the device need to communicate with the substation and the dispatching control center at the same time, and the communication protocol and communication channel reliability are very high.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to an information interaction platform between an intensive DC deicing device and a substation monitoring background information. Background technique [0002] Ice and snow disasters occur frequently in southern regions such as Guizhou, Hunan, and Hubei in China. Due to abnormal climate changes in recent years and even northern regions such as Beijing and Liaoning, ice and snow disasters also occur from time to time. After the transmission line is covered with ice, it is easy to cause tower collapse and disconnection, which seriously threatens the power grid. Safe and stable operation and power supply reliability. In order to improve the ability of transmission lines to resist ice disasters, many domestic units have developed various types of DC ice-melting devices, which provide a solid technical guarantee for the safe and stable operation of the power grid in winter...
