Abstract

The invention discloses a control system of a high and low voltage switchgear. The system comprises a cabinet, a host system monitoring layer, a communication management layer, an onsite protection, measurement and control unit layer and a mobile terminal; the host system monitoring layer comprises a server and a monitoring host, and the monitoring host is used to inquire onsite measurement data, operation data of protectors and operation data of controllers in the server; the onsite protection, measurement and control unit layer comprises measuring devices, the protectors and the controllers in the cabinet, and the measuring devices are used to generate the onsite measurement data; and the mobile terminal is connected to the monitoring host via a wireless network, and checks the onsite measurement data, operation data of protectors and operation data of controllers in the server via the monitoring host. Due to arrangement of the host system monitoring layer and the communication management layer, the onsite protection, measurement and control unit layer in the cabinet can be monitored remotely and automatically.

Description

technical field [0001] The invention relates to a high and low voltage switch cabinet control system. Background technique [0002] At present, the distributed control system (DCS) of power plants led by thermal automation has been widely used, but most of them focus on steam turbines and boilers, and less consideration is given to the electrical system. The control and automation level between the boiler and the electrical system uncoordinated. The electrical automation system of traditional power plants uses physical hard wiring and a large number of hardware devices such as transmitters and I / O cards to collect electrical information and control electrical equipment. Information such as measurement, protection action, setting, and accident recall of the electrical system cannot be accessed on the DCS. Fully responding, it is impossible to realize the functions of electrical analysis and management on DCS. [0003] In the power system of the power plant, each switchgear ...
