現(xiàn)有變電站改造成數(shù)字化變電站時(shí)需要增加過程層設(shè)備，其中對(duì)刀閘接口控制箱的動(dòng)作可靠性提出了極高的要求。提出一種基于雙FPGA實(shí)現(xiàn)多重邏輯閉鎖的刀閘接口控制箱實(shí)現(xiàn)方案。設(shè)計(jì)了FPGA電源和時(shí)鐘實(shí)現(xiàn)電路，兩塊FPGA的信息交換方式以及邏輯互鎖方法。詳細(xì)描述了出口電路自檢方案。介紹FPGA配置和編程方法，給出了FPGA的時(shí)序仿真。測(cè)試了電源建立波形，實(shí)現(xiàn)并驗(yàn)證了裝置運(yùn)行的可靠性。該方案能夠有效防止誤動(dòng)作發(fā)生，適用于有此需求的一般裝置。

　　Abstract:

　　Existing substation transformed into digitized substation when need to increase the process equipment， Interface control box of operating reliability high requirement put forward. Proposed based on double FPGA realizing multiple logical

　　atresic breaker interface control box scheme. Design the FPGA power and clock realization circuit， two FPGA information exchange style and the logic of the interlock method. Detailed descriptions of the export circuit self-check scheme. Introduced the FPGA collocation and programming method， given the FPGA timing simulation diagram， test the power establish waveform， realized and verified the reliable operation of device. This scheme can effectively prevent the misoperation occurs， suitable for the needs of the general device.
