System and method for generating electric pulse trains based on dielectric breakdown

Abstract

The invention discloses a system and method for generating electric pulse trains based on dielectric breakdown. The system comprises an alternating current power source AC, a power source side capacitor C1, a control switch SW, an equivalent loop resistor Z, a load side capacitor C2 and a discharging gap GP; the output end of the alternating current power source AC and one end of a power side capacitor C1 are connected with one end of the control switch SW, the other end of the control switch SW is connected with one end of the discharging gap GP, the other end of the discharging gap GP is connected with one end of the load side capacitor C2 through the equivalent loop resistor Z, and the other end of the load side capacitor C2 and the other end of the power side capacitor C1 are grounded. The actual electromagnetic transient working condition of the electric system isolation switch operation process can be effectively simulated, system-level electromagnetic compatibility experimentation can be performed on electronic transformers and other electronic devices, and the experiment result and the electronic transformer are closer in actual operation condition.

Description

technical field [0001] The invention belongs to the field of high voltage technology and electromagnetic compatibility test, in particular to a system and method for generating electric pulse groups. Background technique [0002] At present, the power grid has developed rapidly towards the smart grid, and the construction of smart substations is also growing rapidly. The construction of the smart grid, which is characterized by automation, informatization and interaction, uses a large number of electronic equipment and optical communication equipment. Represented by electronic transformers, it is a major revolution in electrical equipment in the 21st century. Secondly, various intelligent modules, equipment online monitoring, and automation devices are widely used. However, the application of electronic equipment in the power system must solve the problem of electromagnetic compatibility in its environment, which is the key to the safe operation of the power grid.

Problems solved by technology

[0007] 2. The above tests are carried out individually, not for all test items at the same time;

[0008] 3. The current standard test parameters, such as the amplitude and frequency of voltage and pulse current, are quite different from the actual working conditions of the substation, and the disturbance intensity is significantly lower than the actual operating conditions of the substation;

[0009] 4. The current test is a component-level test and not a system-level test, but it is a system-level test in the actual operation process, and the component-level test cannot fully reflect the working conditions of the system level in actual operation

[0010] According to the above four reasons, the current electromagnetic compatibility test results according to the standard cannot fully meet the actual operating conditions of the substation.
