Abstract

The invention relates to a splitting control method of large-scale regional power grids. The splitting control method comprises steps as follows: (1) a control master station collects an out-of-step message of each transmission node in the power grids through a PMU (phasor measurement unit); (2) when the control master station judges that one section requires splitting according to the out-of-step message uploaded by the PMU, the control master station sends a splitting control command to a splitting terminal unit in a section substation; (3) the splitting terminal unit receives the splitting control command for splitting and simultaneously broadcasts a splitting locking command to other splitting terminal units located on the same electric transmission line passageway; and (4) after other splitting terminal units on the same electric transmission line passageway receive the splitting locking command, the splitting terminal units don't perform splitting no matter whether the splitting terminal units receive the splitting control command sent by the control master station. Compared with the prior art, the splitting control method has the advantages of good harmony, high self-adaptive ability and the like.

Description

Off-the-line control method between the large area electrical network
Technical field
The present invention relates to a kind of off-the-line control method, especially relate to the off-the-line control method between a kind of large area electrical network.
Background technology
Solution train control system between traditional large area electrical network is to obtain each tomography apparatus by different step-out cycle definite values to carry out off-the-line selectivity constantly.But there is following inherent shortcoming in this conventional method: if out-of-step center drop on adjust for longer step-out week after date just move section the time, will delay off-the-line time of a step-out group of planes, in some cases, may cause electrical network to develop into vibration between the multigroup unit.
Summary of the invention
Purpose of the present invention is exactly the off-the-line control method that provides for the defective that overcomes above-mentioned prior art existence between a kind of large area electrical network.
Purpose of the present invention can be achieved through the following technical solutions:
Off-the-line control method between a kind of large area electrical network, this method realizes by the off-the-line terminal installation in the transformer station that is arranged on step-out section both sides between the large area electrical network and controlling center, may further comprise the steps:
1) controlling center is gathered each interior transmission node step-out information of electrical network by PMU (Phasor Measurement Unit, synchro measure unit);
2) the step-out information uploaded according to PMU of controlling center judges that a certain section carries out the off-the-line needs when carrying out off-the-line, sends the off-the-line terminal installation of off-the-line control command to this section transformer station;
3) the off-the-line terminal installation receives the off-the-line control command, carries out off-the-line, and this off-the-line terminal installation is to other off-the-line terminal installation broadcasting off-the-line locking instruction that is positioned on the same transmission line corridor simultaneously;
4) after other off-the-line terminal installation on the same transmission line corridor receives this off-the-line locking instruction, no matter whether receive the off-the-line control command that controlling center sends, all do not carry out off-the-line.
The off-the-line terminal installation that is positioned on the same transmission line corridor all arranges the different off-the-line cycles, whether receives the off-the-line control command with different cycle judgements, and carries out off-the-line.
After the off-the-line terminal installation receives the off-the-line control command, judge other off-the-line terminal installation off-the-line whether that is in same transmission line corridor with it, if the equal off-the-line not of other off-the-line terminal installation, then this off-the-line terminal installation carries out off-the-line.
Compared with prior art, the information that the present invention can collect according to the synchro measure unit that is arranged on each transmission node of electrical network, determine oscillation center, thereby control off-the-line terminal installation carries out off-the-line to the step-out section part in an orderly manner, make whole solution train control system have higher harmony, and for the different off-the-line terminal installations on the same transmission line corridor, be provided with many cover controlling mechanisms, to prevent that a plurality of transformer stations are carried out off-the-line, improve adaptive ability.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
As shown in Figure 1, the off-the-line control method between a kind of large area electrical network, this method realizes by the off-the-line terminal installation in the transformer station that is arranged on step-out section both sides between the large area electrical network and controlling center, may further comprise the steps:
1) controlling center is by each transmission node step-out information in the PMU collection electrical network;
2) the step-out information uploaded according to PMU of controlling center judges that a certain section carries out the off-the-line needs when carrying out off-the-line, sends the off-the-line terminal installation of off-the-line control command to this section transformer station;
3) the off-the-line terminal installation receives the off-the-line control command, carries out off-the-line, and this off-the-line terminal installation is to other off-the-line terminal installation broadcasting off-the-line locking instruction that is positioned on the same transmission line corridor simultaneously;
4) after other off-the-line terminal installation on the same transmission line corridor receives this off-the-line locking instruction, no matter whether receive the off-the-line control command that controlling center sends, all do not carry out off-the-line.
For the off-the-line terminal installation that prevents from being positioned on the transmission line corridor carries out off-the-line simultaneously, this method also is provided with number of mechanisms, to tackle the situation that may occur.Off-the-line terminal installation on same transmission line corridor all arranges the different off-the-line cycles, whether receives the off-the-line control command with different cycle judgements, and carries out off-the-line.For example, have A, B, three off-the-line terminal installations of C on same transmission line corridor, the judgement time in the off-the-line cycle of A is t, B is the t+1 moment, C be t+2 constantly, by judging delay constantly, can prevent because row locking off-the-line when instructing transmission delay to cause.In addition, after the off-the-line terminal installation receives the off-the-line control command, judge other off-the-line terminal installation off-the-line whether that is in same transmission line corridor with it, if the equal off-the-line not of other off-the-line terminal installation, then this off-the-line terminal installation carries out off-the-line.By this multiple testing mechanism, can effectively improve the adaptive ability of whole system, prevent that off-the-line causes the electrical network paralysis simultaneously.
