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.
FIG. 1 is a schematic diagram of a PSD-BPA and PSS/E data conversion program structure provided by an embodiment of the present invention;
the data structure mainly adopts the integral conversion of files, and carries out corresponding conversion according to the type of BPA files and the difference of internal modeling. When the invention is implemented, the method comprises the following steps:
the method comprises the following steps: tidal current data conversion
As shown in FIG. 5, FIG. 5 shows a corresponding relationship between PSD-BPA power flow data and PSS/E power flow data provided by an embodiment of the present invention; the power flow data batch conversion comprises the following steps: the method comprises the steps of alternating current data node conversion, transformer data conversion, generator and load data conversion and two-end direct current line data conversion.
(1) AC data node conversion
In the PSD-BPA power flow calculation program, 13 types of ac nodes are defined, and node data is stored in a B card, a BE card, a BS card, a BQ card, a BT card, a BC card, a BG card, a BX card, and a BT card, respectively, as shown in table 1:
TABLE 1 PSD-BPA node types
Figure BDA0002666275690000061
Figure BDA0002666275690000071
These four node types of the PSS/E are defined as follows: 1 is a non-generator node, 2 is a generator node, 3 is a balance node, and 4 is an isolated node. In actual conversion, the BPA does not meet all 13 node types, mainly including three types of B, BQ, and BS, corresponding to a non-generator node, a generator node, and a balance node, and corresponding parameters are directly filled in during conversion.
(2) Transformer data conversion
Only a double-winding transformer is defined in a power flow calculation model of BPA, and for a three-winding transformer, the three-winding transformer needs to be converted into a combination of three double-winding transformer models after certain conversion. In contrast to BPA, not only the two-winding transformer model but also the three-winding transformer model is provided in PSS/E. When the power flow data is converted, the three-winding transformer model still needs to be converted into a two-winding model. And filling corresponding model parameters when the BPA and the PSS/E are mutually converted.
(3) Generator and load data conversion
The BPA is an ac node filled in by the B card, and the values in the columns 48 to 52 of the card represent the scheduled reactive power values of the generator if the PQ node (B, BC, BF, BJ, BT, BX, BV card) is the PQ node, and the maximum value of the reactive power of the generator if the other node is the PQ node. When data conversion is carried out, the minimum reactive power output QB, the maximum reactive power output QT and the actual reactive power output QG in the PSS/E generator data items are filled according to the node type of BPA, and in addition, the minimum active power output PB needs to be manually set to be-9999. The generator data options of the PSS/E require complex impedances (ZR, ZX) to be filled in. The values of the complex impedances (ZR, ZX) are only used in fault analysis and transient stability calculations, but not in load flow calculations. In the transient stability calculation, if the generator is determined as a transient model, the values of ZR and ZX must be equal to the value of the transient impedance. The generator complex impedance data can be obtained from the transient stability file (. SWI) of the BPA.
The load data of BPA is filled in the AC node card, and the load of PSS/E has special load data record, which is similar to the generator data of PSS/E. The load is expressed by constant power load, constant impedance load and constant current load in BPA, and specific numerical values are stored in an alternating current node data card and a continuation node data card. The PSS/E load data records comprise AREA (AREA) parameters, ZONE (ZONE) parameters and OWNER (OWNER) parameters, and users can classify and output the power flow statistical results according to the AREAs, the ZONEs and the OWNERs.
By comparing the load data in the dat file of PSD-BPA and the raw file of PSS/E, such as the bus name, the active and reactive power of the load, the load type and other parameters, the mapping relation between the corresponding load data in the two files is found out, and the conversion of the load data is realized by writing a program.
(4) Two-terminal DC line data conversion
The two-end direct current line data in the BPA consists of an alternating current node data B card, a two-end tributary node data BD card, a two-end direct current line data LD card, a converter transformer T card and a control data R card thereof. Different from BPA, the direct current line data at two ends of the PSS/E are divided into three groups of continuous data, which are respectively: the controller parameter part, the rectifier parameter part and the inverter parameter part do not need to additionally arrange direct current nodes of the rectifier and the inverter. In addition, the commutation reactance Xc (R, I) of the converter transformer in PSS/E is replaced by the leakage reactance X of the converter transformer in BPA, but the commutation reactance needs to be filled in with the named value that is reduced to the valve side of the converter transformer.
The mapping relation existing between the direct current line data in the two files is found by comparing the direct current line data in the dat file of the PSD-BPA and the raw file of the PSS/E, such as the names of the head end and the tail end of the line, the identifier of the line loop, the resistance and the reactance of the line and other parameters, and the conversion of the direct current line data is realized by writing a program.

Selecting 10 groups of buses with different voltage levels for comparison, wherein the information of a load flow calculation balancing machine of a PSD-BPA simulation system is shown in figure 2, the calculation result of a raw file after load flow data conversion is shown in figure 3, the information of the balancing machine is basically close to the information of the balancing machine of the calculation result of the BPA, the voltage amplitude error is less than 10 < -3 > (per unit value), and the phase angle error is less than 0.5 degrees.
Step two: transient stable data conversion
As shown in fig. 6, it is a corresponding relationship between PSD-BPA and PSS/E transient stability data provided by the embodiment of the present invention, and the transient stability data batch conversion includes: generator model conversion, excitation system model conversion, prime mover and speed regulator model conversion and load model conversion.
(1) Conversion of generator models
The generator models available for selection in PSD-BPA are: 1. consider a two-axis model of the damping winding (sub-transient model); 2. a two-axis model (transient model) without considering the damping winding; 3. classical model E' ═ C; 4. the generator with less influence is represented by an equivalent load (LN card). The generator model in the PSS/E is rich in types, including GENCLS (classical model), GENTRA (salient pole machine transient model), GENSAL (salient pole machine secondary transient model), GENROU (non-salient pole machine secondary transient model), GENSAE (salient pole machine secondary transient model of index saturation curve), GENROE (non-salient pole machine secondary transient model of index saturation curve), and GENDCO (non-salient pole machine secondary transient model considering stator transient). During conversion, firstly, the generator capacity of the corresponding bus is read in the raw file, then the generators with the same or similar capacity are searched in the raw file, and finally the generator parameters with the same or similar capacity are read in the dyr file and replaced by the parameters.
(2) Conversion of excitation system model
Excitation system models in PSD-BPA (phase-sensitive detector-phase-locked loop) EA card, EB card, EC card, ED card, EG card, EK card, FJ card and PSS/E are similar to each other approximately; EE card, EF card and F (M-V) card have no corresponding excitation system model in PSS/E data file. The excitation system model in the PSD-BPA only needs to be directly converted from the corresponding similar model, and the corresponding PSS/E excitation system model is compiled by contrasting with the standardized excitation system model in the PSD-BPA without the function of the customized model in the PSS/E corresponding to the similar model. A fully matched excitation system model is shown in table 3.

(3) Comparison and conversion of prime mover to governor models
The model of the prime motor and the speed regulator in PSD-BPA can be respectively arranged or fixedly combined, the prime motor and the speed regulator in PSS/E are a combined model, and the table 4 is a comparison table of the models of the prime motor and the speed regulator in PSD-BPA and PSS/E.

GC CRCMGV Speed regulator and prime mover model of double-shaft steam turbine generator
GH IEEEG3 Governor for hydraulic turbine and prime mover model
GW+TW IEEEG2 Governor for hydraulic turbine and prime mover model
(4) Comparison and conversion of load models
The load model in PSD-BPA is divided into: algebraic models (LA and LB), new static load models (LA, LB and their continuation cards L +), induction machine Models (MI), new induction machine models (MI, MJ, MK) and a comprehensive load model (LE) taking into account the branches of the distribution network. The load model of the PSS/E provides not only the usual static compliance and dynamic load models, but also low voltage load shedding and low frequency load shedding models.
Equations (1) to (4) are algebraic relations of a static load model commonly used for BPA.
Static load model LA:
P＝P0[P1V2+P2V+P3+P4(1+DfLdp)] (1)
Q＝Q0[Q1V2+Q2V+Q3+Q4(1+DfLdp)] (2)
static load model LB:
P＝P0(P1V2+P2V+P3)(1+DfLdp) (3)
Q＝Q0(Q1V2+Q2V+Q3)(1+DfLdp) (4)
for the LA model the data set consists of: p1+P2+P3+P4＝1.0，Q1+Q2+Q3+Q4＝1.0
For the LB model consists of: p1+P2+P3＝1.0，Q1+Q2+Q3＝1.0
The algebraic relations of the static load model IEELBL in the PSS/E are shown in the following formula (5) and formula (6):
P＝P0(a1Vn1+a2Vn2+a3Vn3)(1+a7Df) (5)
Q＝Q0(a4Vn4+a5Vn5+a6Vn6)(1+a8Df) (6)
wherein: p is the active power of the load model; p0Is the initial active power; p1Is a constant impedance active load proportion; p2Is a constant impedance active load proportion; p3Constant power active load proportion; p4Is the frequency dependent active load proportion; q is the reactive power of the load model; q0Is initial reactive power; q1Is a constant impedance reactive load proportion; q2Is a constant impedance reactive load proportion; q3Constant power reactive load proportion; q4Is the reactive load proportion in relation to the frequency; l isdp\a7Percentage active change due to 1% frequency change; l isdq\a8Is 1% of the frequency variationPercent reactive change induced; v is bus voltage; Δ f is the frequency variation; a is1+a2+a3＝1.0， a4+a5+a6＝1.0；
As can be seen from the above algebraic relations, there are some differences between the LA model of PSD-BPA and the IEELBL model of PSS/E, and the LB model and IEELBL model are identical. The frequency-dependent part of the LA model is generally used less often, so by letting P of the LA model1＝Q 10, it can also be converted to the static load model IEELBL of PSS/E.
Based on the principle analysis, the user-defined model is subjected to simulation test. As shown in FIG. 4, the error is believed to be due to the difference between the two pieces of software, since the custom model is substantially close to the BPA model. The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
