PROBLEM TO BE SOLVED: To reduce the tolerance of a flatness degree in stripping operation. SOLUTION: This is a method which can be used to control the flatness degree of a strip 1 comprising a rolled material. In the method in which the measured value of the flatness degree of the step 1 obtained at least in one region after passing through a rolling portion 5 is used to control the flatness degree of the rolled material by comparing with the target value of a first prescribed rolling flatness degree and to generate a controlling signal of the rolling portion 5 for adjustment, the target value of the flatness degree at least in one region is made to provide a method charaderizing a further step comprising the target value of the rolling flatness degree which is made to rely on a second longitudinal direction for strip 1 which is forced to rely on the position of the longitudinal direction of the strip.

PROBLEM TO BE SOLVED: To provide a simple, satisfactory method capable of maintaining the voltage of DC links within a safety operation limit even under an abnormal state and a control system for performing the method. SOLUTION: Converting facilities (STN1, STN2) having voltage-converting devices (CON1, CON2) are provided between DC links (W1, W2) and AC networks (N1, N2) of a high voltage DC transmitting system. Control systems (CTRL1, CTRL2) of the converting facilities have means for controlling a dynamic electric power flow (P) between the DC links and the AC networks by having an effect on phase difference (γ) between the bus voltages (UL1, UL2, UL) of the AC networks and the bridge voltages (UV1, UV2, UV) of the voltage- converting devices. The control systems have a detecting means (48) that generates a phase change command signal (PCO) based on an abnormal voltage state index at the DC links, and a control means (49) that has effect on the phase of the bridge voltages based on the phase change command signal and control, in such a way that the phase difference between the bridge voltages and the bus ones becomes the electric power flow from the DC links to the AC networks.
