Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, the in-situ relay protection reliability control device provided by the present invention includes two completely independent control modules, which are respectively called the main control module and the start-up control module for their respective functions. In this embodiment, the two control modules are two completely independent CPU systems installed on one board. Correspondingly, these two CPU systems are respectively called the main CPU and the startup CPU.

[0020] In order to save space, the CPUs in these two independent CPU systems are CPU chips with high integration and low power consumption, such as the chip ZYNQ7020, which is integrated with FPGA, and the peripheral RAM, Flash and other devices of each CPU chip are also completely independent. . Using a highly integrated chip, on the basis of satisfying the hig...

Abstract

The invention relates to an on-site relay protection reliability control apparatus and a relay protection method. A starting control module is used for performing starting logic discrimination according to received corresponding data information; a main control module is used for performing protection logic discrimination and starting logic discrimination according to received corresponding data information; and when the starting logic discrimination performed by the starting control module and the main control module are both in action, and the protection logic discrimination performed by the main control module is in action, a protection action signal is output. The relay protection way is performed by two layers of logic discrimination; and firstly, a condition that the two starting logic discrimination are both in action is satisfied, and the protection action signal is output according to the protection logic discrimination only after the two starting logic discrimination are in action, so that the relay protection method lowers possibility of on-site protection faulty action, thereby still satisfying relay protection high-reliability requirement in an extremely severe operation environment.

Description

technical field [0001] The invention relates to an in-situ relay protection reliability control device and a relay protection method, and belongs to the technical field of in-situ relay protection for power systems. Background technique [0002] The relay protection device is an important part of the power system, and it plays a very important role in ensuring the safe operation of the system. When the system fails, it removes the faulty equipment and contributes to the safe operation of the system, but the incorrect action of the relay protection also causes great harm to the system. Relay protection devices require the unity of reliability, selectivity, sensitivity and rapidity, among which reliability is the most important requirement for relay protection devices. [0003] The in-situ protection device is directly installed in the switchyard or integrated with the primary equipment. Due to the direct outdoor unprotected installation method, the operating environment is h...
