In order to effectively control the fluctuation amplitude of electric quantity pulse and realize the on⁃demand dispatching and coordination of substation transmission signals,an intelligent substation multi⁃level joint commissioning control system is designed based on telemetry technology.Integrate the electric quantity transmission signal in the multi⁃level substation control circuit,distribute it to two types of application equipment components,namely,the joint debugging modem and FPGA module,and complete the hardware operation environment of the multi⁃level joint debugging control system in the intelligent substation.According to the principle of telemetry technology,determine the initial value of telemetry phase,improve the specific execution process of multi⁃level joint control command according to the solution result of substation pulse intensity index,and then combine the relevant hardware structure to complete the design of multi⁃level joint commissioning control system of intelligent substation.The comparative experimental results show that under the effect of telemetry technology,the maximum amplitude of electric power pulse signal of the designed system reaches 3.05×10^(-9) mm/ms,the system can effectively control the fluctuation amplitude of electric power pulse,meeting the application requirements of coordinating the transmission signal of substation on demand.
