The invention discloses a distribution network protection and automatic device cooperating method based on DG characteristics. According to the method, action levels are divided into a fault isolation level, a spare power automatic switching intercutting DG level and a low-frequency low-voltage intercutting partition islet level in space, whether an islet is allowed to operate or not is determined according to the balance capacity of DG local loads, and fast islet division is achieved automatically through a low-frequency low-voltage intercutting fixed value to guarantee stable operating of a power system and reliable operating of the local loads. Meanwhile, a protection fixed value considers that even though DG is in an islet operating state and breaks down, a protection device can act fast and accurately to remove the fault. Regional information is adopted as coordinating factors and is used for overcoming the defects of separation of a relay protection and automatic device and a DG operating work condition, division of the islet extending layer by layer is determined according to the trend distribution of a power source and loads after fault current removing and the changes of a network topology structure, and a coordinating distribution type power source protection scheme system is formed.

A Coordination Graph Dual-Arm Collaborative Control Method Based on Fusion of Human Kinematics Constraints

The invention discloses a coordination diagram dual-arm cooperative control method based on the fusion of human kinematic constraints. The invention simultaneously performs dual-arm cooperative control from the action level and the operation task level; Collaboration trajectory, using the quaternion attitude trajectory mapping method to map human actions to the robot side and optimize storage; generate a coordination diagram according to the trajectory collision situation, the coordination diagram uses the operation time of the left and right arms as the horizontal and vertical coordinates, and the robot in the setting diagram will collide Robot configurations are black and collision-free configurations are white, forming a complete coordination map. In the coordination graph, the RRT‑Connect algorithm is combined with the trajectory optimization algorithm in the open source motion planning library for trajectory planning to complete the dual-arm cooperation at the motion level. After the collision-free cooperative pair operation is completed, the collision-prone cooperative pair cooperates according to the calculation results of the previous cooperation law to complete the cooperative operation, so that the operation time is minimized and the operation efficiency is maximized.
