Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The concept of parent section and child section is introduced into the section. The child section has its own mode and limit information, and the section information is the same as the parent section. The mode and the limit information of the father section are the content of the child section which meets the mode at present. Once the section power is out of limit, the section operation mode is changed, and a dispatcher is reminded in time through information such as color change, flashing, alarming and the like.
As shown in FIG. 1, the parent cross-section reference sub-cross-section program logic is as follows:
judging the parent section state and the default sub-section mode,
1) if the father section state is' manual stop, the son section state does not need to be judged, and the actual section value of the father section is still calculated and sampled.
2) If the father fracture surface state is not 'manual shutdown' and the default child fracture surface mode is not satisfied, the father fracture surface state is 'program shutdown'.
3) The father fracture surface state is not 'manual stop', the default child fracture surface mode is satisfied, and the father fracture surface state is 'start', and the following judgment operation is carried out:
if only one non-default section is satisfied, the parent section refers to the non-default section;
if more than one non-default section is met, the parent section refers to the non-default section with small section limit;
if no non-default section is satisfied, the parent section refers to the default section.
The judgment logic of optimizing the running state of the equipment is added, the system can automatically obtain the running states of the line, the main transformer and the bus, and the simple and accurate definition and judgment of the running mode of the section are facilitated.
If both ends of the line are running, the line is running, otherwise, the line is not running; there is a line with an end node number of-1: if the end with the node number is running, the line is running, otherwise, the line is not running;
coloring the bus according to topology, wherein the main island or the sub-island is operated, and the other main island or the sub-island is not operated;
if the two rolls run at high and low positions, the main transformer is operated, otherwise, the two rolls are not operated; if the three rolls run both high and medium, the main transformer is operated, otherwise, the three rolls are not operated;
and when the program judges the running state of the equipment, judging that the equipment does not run when the topology coloring of the equipment is a non-main island. But the scheduling considers the system to be in a split state, so the device topology coloring is judged to be running when the device topology coloring is a main island or a sub-island. And the device is judged to be not operated only when the topology coloring of the device is power failure or grounding.
The program implements the logic:
1) firstly, judging whether the topology is power failure or grounding, and if so, judging that the topology is not operated;
2) if the topology of the equipment is not power failure or grounding (namely, the equipment comprises a main island, a sub-island and suspicious grounding), judging that each end is connected with the equipment:
if one end at least comprises a line, a transformer, a generator and a load, the topology of which is a main island or a sub-island or can be suspected to be grounded, the end is judged to be operated; otherwise, judging the end as exit.
When the sub-section of the current satisfying mode changes, the system can judge the sub-section of the original satisfying mode and the sub-section information of the current satisfying mode according to the operation mode information of the sub-section and display the popup frame.
The box popping prompt decision logic is as follows:
and (4) prompting without popping a frame: the parent section refers to the child section at present and does not change, and the number of the child sections meeting the conditions does not change;
and (4) frame popping prompt: the parent section refers to the child section at present and does not change, and the number of the child sections meeting the conditions changes; the parent section currently refers to the child section to change, and the number of the child sections meeting the conditions changes; the parent section currently refers to the child section to be changed, and the number of the child sections meeting the condition is not changed, as shown in fig. 2.
When a parent section and a child section are defined through a section definition tool, the system can automatically perform sampling definition on corresponding domains, the sampling period is 1 minute, manual definition operation is omitted, and the problem of sampling omission is avoided. The method can analyze the actual operation condition of the section aiming at the sampling data, quote the relevant information of the section when the section is changed, and the report system can quote the relevant data, and can carry out deep analysis on the basis, thereby providing powerful support for the operation of the power grid.
