The invention discloses a pulse frame transmitting and receiving method, which provides framing proposal for pulse frame positioning measurement. The technical proposal includes that the transmitting and receiving method includes that a principle and subordinate end pulse frame transmitting process includes that pulse on transmitting end starts the framing of pulse frame; the framing proposal is determined according to pulse frame coding; the coding form of independent pulse part enables the pulse part to be transmitted separately; the pulse frame simultaneously transmits data in prior periodaccording to coding measurement transmission time of pulse part; the principle and subordinate end pulse frame receiving process includes that pulse part of pulse frame is received separately; the validity check is performed on the pulse part of the pulse frame separately; if the pulse part passes the validity check, the pulse frame starts to receive time measurement; otherwise, the next pulse frame ...

The invention discloses a black-start method, which realizes the improvement of the rapid recovery of a grid and ensures system stability and equipment safety during the black-start process. The invention is achieved by the following technical proposal: in the black-start method, first, taking a large-capacity thermal power generating unit as black-start power supply to impact a large-capacity transformer with the power supply capacity less than that of the black-start power; then gradually restoring the significant load power supply, controlling the current to impact the load transformer towards a lower voltage level progressively, and carrying out power supply to the next electricity grid by the load transformer; and then gradually restoring the power supply to the partition power grid and the district power plants, and transferring electric current to other thermal power generating units with the same voltage level so as to provide electricity necessary for the operation of the corresponding ...
