| As technology advances and society, the importance of energy in people’s lives will stand out, along with the quality of electricity customers growing demands and getting better. Driven by the power system automation rapid development, construction scale grid system becomes increasingly large, which makes the power system has a more complicated mode of operation. In the power supply system protection, the BZT device plays a very important role, when the power system protection devices cut bad running state or failed power supply, spare power automatic switching device is capable of real-time, fast action to make the load by standby power out, so as to avoid the accident and effectively improve the continuity and reliability of the power supply system.Driven by the development trend of the power supply system so that the standby power automatic switching device logic operation is becoming increasingly complex, increasingly stringent operation requirements.In this paper, automatic standby power switching device the following three research areas:backup power automatic switching hardware configuration of the device, Auto Power Switch Device software design and application of BZT device in the current power system. In terms of hardware, introduces its overall structure, the device terminals and description, value content and its setting instructions, including system parameter tuning method, protection setting method and communication parameter setting method, the auxiliary parameter setting method setting; in software, software in BZT body of the device into the programmable logic device introduced in different algorithms applications, including Half-wave Fourier Algorithm design of software programs in the following areas it covers primary procedures, exchange of data acquisition program, terminate the program and communication program. BZT device in practical applications, it has a flow blocking malfunction conducted in-depth research and found a solution. |
