Problems solved by technology

Once the supply is cut off, there will be no accessory support for the relevant relay protection devices in operation, and all new protection devices must use domestic components
[0003] Since the safe operation of the power grid is highly dependent on reliable secondary equipment, and the localized protection equipment is still in the development and pilot stage, it is not yet mature, which will lead to a sharp increase in the risk of large-scale grid collapse and power outages in the power system, and the large-scale interconnected grid may be disconnected and reduced. The physical foundation of the three lines of defense for grid security and stability will face major challenges
[0004] In view of the existence of the above-mentioned existing technologies, because the safe operation of the power grid is highly dependent on reliable secondary equipment, and the localized protection equipment is still in the development and pilot stage, it is not yet mature, which will lead to a sharp increase in the risk of large-scale grid collapse and power outages in the power system. The large interconnected power grid may be disconnected and operated at reduced voltage, and the regulation and control ability of the power grid will drop sharply. The physical foundation of the three lines of defense for the safety and stability of the power grid will face major technical challenges. No effective solution has been proposed yet.

Abstract

The invention discloses a relay protection platform hardware design method and system based on component reliability. The method comprises the following steps: determining the reliability of the relay protection device as [Pi]R; according to the reliability [Pi]R of the relay protection device, determining that the fault rate P<0> of the statistical analysis system corresponding to the relay protection device is equal to 1-[Pi]R; evaluating the components of the relay protection device, and determining the fault loss cost of the relay protection device; comparing the fault loss cost of the mature relay protection device with the fault loss cost of the newly researched and developed relay protection device, and when the newly researched and developed relay protection device has an optimization space, determining the optimization space cost; carrying out redundancy design on the newly researched and developed relay protection device, and determining that the reliability of the newly researched and developed relay protection device after redundancy design is [Pi]R; and comparing the reliability [Pi]R of the newly researched and developed relay protection device after redundancy design with the reliability [Pi]RH of the mature relay protection device, and determining that the technology of the newly researched and developed relay protection device is feasible.

Description

technical field [0001] The present application relates to the technical field of power systems, in particular to a hardware design method and system for a relay protection platform based on component reliability. Background technique [0002] Relay protection is an important part of ensuring the safe operation of the power grid, while analog-to-digital conversion chips (ADC), main control chips (MCU, CPU, etc.), programmable logic device chips (FPGA), communication interface chips, memory chips, isolation chips And other industrial-grade chips are the core devices of secondary equipment. The above-mentioned chips are widely used in substation relay protection devices, automation equipment, communication equipment and other secondary equipment, covering the entire power grid. Once the supply is cut off, there will be no accessory support for the relevant relay protection devices in operation, and all new protection devices must use domestic components. [0003] Since the sa...
