Embodiment Construction
[0020] The invention will be further elaborated below in conjunction with the accompanying drawings, and the method proposed by the present invention improves the opening and entering circuit of the long-distance jump device. Refer to the attached schematic diagram for the principle diagram of the action criterion of the long-distance jump device. figure 2 , in order to use the three-phase series TWJ circuit of two circuit breakers connected to the same line as the device action criterion, when both circuit breakers are disconnected, the device satisfies the action logic, and the device outlet circuit is opened to perform tripping action. Jump off the relevant components, and at the same time send a remote jump command to the device on the opposite side of the line to jump off the relevant components. as attached image 3 As shown in , in the present invention, the three-phase series TWJ of the two circuit breakers connected to the same line in the remote jumper is connected...

The invention relates to a method for realizing continuous jumping of multi-level components of a power grid. The long-jump device installed on the line is used to install the long-jump device at the first section of the next-level line, and the circuit breaker connected to the end of the upper-level line The TWJ of the circuit breaker and the TWJ of the circuit breaker connected to the first section of the line at this level are respectively connected to the corresponding circuit. The invention utilizes the long-distance jump device, and because the long-distance jump device has the technical characteristics of simple circuit, safety and reliability, the maturity of the device is relatively high. Using the device to solve complex grid problems can realize correct actions and achieve expected goals. The invention improves the action criterion of the long-distance jump device, through the improvement of the action criterion, it breaks through the limitation of the original "one-to-one" supporting action, expands the function of the original long-distance jump device, and can comprehensively deal with complex power grid problems .
Description
technical field [0001] The invention relates to a method for realizing continuous jumping of multi-level components of a power grid, more specifically a method for realizing disconnection of a faulty power grid when a line fails by using a long jump device. [0002] technical background: [0003] With the continuous advancement of power grid construction, power supply grids to remote areas continue to form, but the network structure at the end of the power grid is extremely weak, and in the network for power supply to remote areas, especially the power grid with a voltage level of 500kV and above, due to the general power transmission lines Long, in order to eliminate the impact of long-distance power supply line capacity rise effect on the grid voltage, a large number of high-voltage reactors are installed along the line and substations. Once a disconnection fault occurs in the power grid, due to the action of the high-voltage reactor, the related power grid will have grid o...
