The purpose of state stability simulation.
The present invention adopts the following technical scheme that to achieve these goals：At a kind of transient stability operation based on PSASP
Manage optimization method, it is characterised in that comprise the following steps：
1) the transient stability operation for treating batch processing is selected；
2) judge the type of transient stability operation, total data table corresponding with the operation is read according to type；
3) according to default starting point, terminal and interval, in the corresponding data position in corresponding tables of data batch is carried out to repair
Change, so as to realize the batch processing to transient stability operation.
Further, the method for the type for judging transient stability operation is according to type in st_dist_inf tables
The value selection st_dist_t form reading operations of field.
Further, it is described corresponding with operation total data table is read according to type to include, if cutting machine operation then
Tables of data st_dist_t5 is gone to, tables of data st_dist_t7 is then gone to if circuit homework is cut.
By adopting the above-described technical solution, the present invention has the advantage that：
1. the corresponding data position in the corresponding data table of backstage is directly changed, to reach the purpose of batch processing.Can be right
Transient stability operation in PSASP softwares carries out batch processing, improves operating efficiency.
2. directly finding out and changing the numerical value of respective field in tables of data, it is from the essential concept of PSASP softwares, uses
The method that reverse thinking is obtained, there is the advantages of reliable, record property is strong.
3. this method has the advantages of hommization, user according to specific demand, voluntarily set the starting point of failure, terminal and
Interval.
Other advantages, target and the feature of the present invention will be illustrated in the following description to a certain extent, and
And to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, Huo Zheke
To be instructed from the practice of the present invention.The target and other advantages of the present invention can be wanted by following specification and right
Book is sought to realize and obtain.
Brief description of the drawings
Fig. 1 is the program flow diagram of the present invention；
Fig. 2 is the pie graph of transient stability operation；
Fig. 3 is transient stability operation membership figure.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the program flow diagram that a kind of transient stability operation based on PSASP provided by the invention handles optimization method,
Include following sequential steps：
Step 1：The selected transient stability operation for treating batch processing of user；
Step 2：The tables of data with pending transient stability operation is read, and judges transient stability homework type, goes to phase
The tables of data answered carries out batch processing；
Step 3：Tables of data st_dist_t5 is then gone to if machine operation is cut, tables of data is then gone to if circuit homework is cut
st_dist_t7；
Step 4：Pending homework type according to selected by user, the Mass production K_ratio in corresponding tables of data,
Cut machine or cut cut-out point position in circuit homework, its span is 0 to 1；
Step 5：Update the data table and replicate and generate other tables of data.
The method that homework type is judged in the step 2 is to be selected in st_dist_inf tables according to the value of type fields
St_dist_t form reading operations.
Mass production K_ratio mode is to set starting point, terminal and interval by user in the step 4, then passes through letter
Single programming causes K_ratio since threshold value, adds a spacing value to generate a new K_ratio, until reaching terminal
Value, Mass production K_ratio task is completed with this.Among it every generally 0.1 or 0.05.
Tables of data in the step 5 is st_case, st_fault, st_dist_inf, st_dist_t5, st_
It is one or several in dist_t6, st_dist_t7.
Fig. 2 is the composition of transient stability operation, and the transient stability operation that PSASP is defined is by Power Flow Information and transient stability control
Information data processed is formed；
Transient stability includes network failure and node disturbs two kinds of operation, and network failure includes single-phase connect
Ground, single-phase wire break, three-phase ground and broken string, need to set the position of fault and position of failure point when defining operation；
Node disturbance failure mainly includes impact load, quick regulation, cuts the disturbance type such as machine-cut load.Wherein, save
Point disturbs failure and cuts the disturbance variable that machine, cutting load are frequently necessary to adjust manually under study for action.
Fig. 3 is transient stability operation membership, and tables of data st_case contains all transient state operations；
Ctrl_fault fields in st_case represent whether the operation belongs to network failure, if then corresponding to number
According to table st_fault；
Ctrl_dist fields in st_case represent whether the operation belongs to disturbance failure, if then corresponding to data
Table st_dist_inf；
Type fields in st_dist_inf represent the disturbance type of the disturbance operation, cut machine operation and correspond to data
Table st_dist_t5, cutting load operation correspond to tables of data st_dist_t6, cut circuit homework and correspond to tables of data st_dist_
t7。
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to compared with
The present invention is described in detail good embodiment, it will be understood by those within the art that, can be to the skill of the present invention
Art scheme is modified or equivalent substitution, and without departing from the objective and scope of technical scheme, it all should cover the present invention's
Among right.
