Abstract

The invention discloses a constant value comparison device for obtaining constant value parameters through the printing port of relay protection equipment. The equipment running constant value information of protection equipment is collected passively through the printing port of relay protection equipment by means of an acquisition terminal device. A background management server manages the acquisition terminal device through an Ethernet network, and then the network parameters of the acquisition terminal device are set. In this way, the operation state of the acquisition terminal device is displayed in real time. The equipment running constant value information of the protection equipment is called by the acquisition terminal device. Meanwhile, the equipment running constant value information of the protection equipment is automatically compared with the imported newest constant value information of a dispatching mechanism. The comparison result is displayed, printed and outputted. According to the invention, by means of the constant value comparison device, the manual printing and checking of paper files by people is replaced by the operation of the constant value comparison device, so that the error probability is reduced. The labor cost is saved, and the working time is shortened. The working efficiency is improved. The operation safety and the operation reliability of therelay protection equipment are improved.

Description

technical field [0001] The invention relates to a detection device of an electric power system, in particular to a fixed value comparison device for obtaining fixed value parameters through a print port of a relay protection device. Background technique [0002] Relay protection device is an automatic measure and equipment. When the power components in the power system (such as generators, lines, etc.) or the power system itself fail to endanger the safe operation of the power system, it can send a warning signal to the operator on duty in time, or directly send a trip command to the controlled circuit breaker to stop these developments. The relay protection device is used to monitor the normal operation of the power system. When the protected power system component fails, the relay protection device of the component should quickly and accurately issue a trip command to the circuit breaker closest to the faulty component, so that the fault The components are disconnected f...
