Embodiment Construction
[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] The embodiment of the machine cutting method of round-by-round recursion:
[0023] This embodiment provides a round-by-round recursive cutting method. This cutting method no longer uses the traditional one-round cutting mode, but after the current round of cutting is completed, the required cutting amount and the detected The actual cutting amount is compared, and if the difference between the two is greater than the set threshold value of the current round, the set cutting strategy is re-run for the next round of cutting, and this is repeated until the actual cutting amount reaches the expected effect . Specifically, the flow chart of the round-by-round recursive cutting method is as follows: figure 2 shown, including the follow...

The invention relates to a cutting machine method and a device which are recursively pushed in turn. The method comprises: according to the required cutting amount of the cutting machine, the cuttingmachine is operated according to a set cutting machine strategy; After the operation of the wheel cutting machine is completed, the actual cutting amount of the wheel cutting machine is detected, andwhether the difference between the required cutting amount and the actual cutting amount of the wheel cutting machine is greater than the set threshold value of the wheel is judged, and the set threshold value of the wheel is the maximum value of the cuttable power of each branch in the operation of the wheel cutting machine; If it is larger than the set threshold value of the current round, the difference is taken as the required cutting amount of the next round of cutting machine, and the next round of cutting machine operation is carried out until the difference between the required cuttingamount of the current round and the actual cutting amount is not greater than the set threshold value of the current round. The invention adopts the machine cutting mode of recursive wheel by wheel,and through the real-time adjustment of the set threshold value, the cutting error is minimized, and the stability of the electric power system is ensured.
Description
technical field [0001] The invention relates to a wheel-by-wheel recursive cutting method and device, belonging to the technical field of power system safety and stability control. Background technique [0002] With the gradual expansion of the grid scale of the power system and the popularization and application of the AC-DC hybrid mode, the importance of safe and stable operation of the grid is becoming more and more important. The deployment and application of the power grid security and stability control system is an important measure to ensure the complete and stable operation of the power grid, and when the system is unstable, it is possible to perform precise cut-off operations according to the required cutting amount calculated by the strategy to determine whether the power grid security and stability control system can fully play its role key. [0003] Judging from the actual application situation, it is difficult to guarantee the precise cutting operation accordin...
