The invention belongs to the technical field of power system relay protection and particularly relates to a DC line relay protection method for a multi-terminal flexible medium-voltage DC power distribution system. The method comprises the steps of main protection and the backup protection. The main protection reflects an inter-electrode short-circuit fault of a DC line and a unipolar grounding fault of a small transition resistor, wherein a fault type and a fault interval are identified based on a current state matrix. The backup protection adopts the duration of the voltage imbalance as a starting criterion, so as to protect a judging fault interval of positive and negative current imbalance state matrixes at an installation part and isolate faults. The method determines the action signal of a DC breaker according to the switching-on/off signals of the main protection and the backup protection. The main protection only depends on the status signal values -1, 0 and 1 of two adjacent protection and transmission current elements, so that the requirement on a communication system is reduced. The backup protection judges the occurrence of a fault only based on the voltage, wherein the unbalanced current calculation is aiming at the positive current and the negative current of the same protection part. Therefore, the generation of errors due to the communication delay or the non-synchronized communication can be avoided.

First order gradient errors are canceled with no current source splitting by placing consecutive current sources symmetrically around the center of the array. Consecutive elements that correspond to small input amplitudes (mid-scale codes) make a smaller spatial jump than those correspond to larger signal amplitudes. Both linear and second order gradients are reduced by splitting each current cell into two and placing sub-elements symmetrically with respect to the center of the array to address the linear gradient effect. To address second order gradients, current element placement follows a pattern such that consecutive element pairs are chosen with one of the pair being placed with respect to the zero error contour of the second order gradient so as to have a positive error and the second of the pair being placed so as to have a negative error resulting in reduced second order error accumulation.
