Detailed Description
To make the structure and advantages of the present invention clearer, the structure of the present invention will be further described with reference to the accompanying drawings.
Example one
In order to increase the pressure and challenge on the operation management of a power grid along with the continuous development of the power industry in China, the power grid structure is more and more complex, the power grid regulation and control integrated operation is the inevitable choice of the power grid operation management, and a power grid regulation and control integrated simulation system is used as an auxiliary tool for the power grid dispatching operation and is also more and more applied. The power grid regulation and control integrated simulation is that the simulation operation environment from a transformer substation to a dispatching end power grid is built, the processes of generation, transmission, cooperation, control, disturbance and the like of various signals of the power grid are simulated, and simulation results are displayed in various modes such as imaging and the like, so that the support effect on personnel training and examination, operation auxiliary analysis, debugging and verification and the like is achieved.
The signal simulation is an important content of a power grid regulation and control integrated simulation system, a large number of signals need to be established for carrying out fine simulation on power grid equipment, however, the real-time performance of the system is affected due to excessive signal quantity, the engineering difficulty is greatly increased, and the problem of how to extract information contained in the signals and not generate excessive signals is a difficult problem faced by the simulation system.
Based on the above background, the present invention provides a signal quantity simplification method for a simulation system based on single-point multiple-phase, as shown in fig. 1, the signal quantity simplification method includes:
firstly, when a simulation operation model is established, selecting equipment types and operation templates of primary equipment and secondary equipment, and establishing a remote communication opening point and a remote communication opening point according to a preset dynamic data structure based on attribute self-description;
secondly, associating a remote signaling switching-out point on the primary equipment with a remote signaling switching-in point on the secondary equipment according to the actual wiring condition of the simulated object, and establishing a corresponding relation between signals of the primary equipment and the secondary equipment;
thirdly, a real-time library loading program in the simulation system loads the remote signaling records in the database into the real-time library, state information of remote signaling opening points is obtained, and algorithm functions in a remote signaling calculation algorithm library are called to generate state information corresponding to the opening points according to the connection relation;
and step four, sequentially starting subsequent simulation programs to complete simulation initialization.
In implementation, the power system equipment comprises primary equipment, secondary equipment, a monitoring system and the like, and the state and control information of the primary equipment and the secondary equipment needs to be accessed to the substation monitoring system through the secondary equipment (a measurement and control device, a merging unit, an intelligent terminal and the like) with a measurement and control function or sent to the intelligent scheduling support system through telemechanical equipment.
Taking the example that the primary and secondary equipment telemetering, remote signaling and remote control information are accessed into a transformer substation monitoring system (the access to the intelligent scheduling support system also needs telemechanical equipment). For traditional primary equipment, sampling data and state monitoring information need to be accessed into a transformer substation monitoring system through a measurement and control device, for traditional protection devices for protecting high-voltage equipment of 110kV and above 220kV, the device sampling does not generally have a monitoring function in order to meet the requirements of the protection function, signals after the equipment action are sent to a signal protection system or a transformer substation monitoring system in a protection soft message mode, and partial central signals need to be sent to the measurement and control device through a hard cable connection mode, and are finally sent to the transformer substation monitoring system through the measurement and control device.
The specific content in the step one comprises the following steps:
101. selecting the type of primary equipment, including equipment such as a transformer, a circuit breaker, a disconnecting switch, a power transmission line, a bus, a voltage transformer, a current transformer, a capacitor, a reactor, a high-voltage reactor and the like,
102. selecting the primary equipment operation template, setting a dynamic data structure definition rule according to the attribute self-description by a simulation modeling tool according to a program, and creating various monitoring signal points, namely starting points, which are consistent with the primary equipment operation template in a primary equipment remote signaling definition table, wherein the remote signaling points are phase points;
103. selecting the type of secondary equipment, including a measurement and control device, a protection and measurement integrated device and the like;
104. and selecting the secondary equipment operation template, and establishing a remote signaling opening in point and an opening point which are consistent with the secondary equipment operation template in a secondary equipment remote signaling definition table by a simulation modeling tool according to a dynamic data structure definition rule set by a program and described by attributes, wherein the remote signaling point is not a phase point.
The remote signaling proposed in this embodiment refers to a process of sending an alarm signal and a switch position signal to a monitoring system. In the process, the breaker is switched on, and the switching-off position is the remote communication quantity.
The state information in step three includes the position information of the open point and the open point on different devices, and also includes other information of each contact on the primary device and the secondary device.
In the process, by using a special connection mode between the primary equipment and the secondary equipment, a signal acquisition mode of eight sampling points in the prior art can be completed by using only two sampling points, and meanwhile, a dynamic data structure based on attribute self-description is used, so that data representing multiple meanings are transmitted by using the same data format, the data compatibility is ensured, the probability of generating redundant data is reduced, and the simulation effect of the simulation system is improved.
Optionally, the dynamic data structure includes:
the status information of the device is represented by an integer number of 4 bytes,
in order to be compatible with other remote signaling signals which still adopt one Bit to represent a specific state, the 17 th Bit and the 18 th Bit represent the attribute of the state, wherein 0 represents that the signal is a single-point single-phase signal, 1 represents that the signal is a single-Bit single-phase signal, 2 represents that the signal is a double-Bit single-phase signal, and 3 represents that the signal is a triple-Bit single-phase signal.
In the implementation, in the power grid regulation and control integrated system,remote signalling signals being of a basic data typeThe device position, signal state, and the like are mainly indicated, and generally, only two states are indicated by the switching value 0/1. In an actual medium-scale 220kV station end monitoring system, the number of remote signaling measuring points is nearly ten thousand, and the monitoring point signals of primary equipment are not included, but in a power grid regulation and control integrated simulation system, if the two parts of signals are completely modeled, the number of the remote signaling measuring points is often 20000+, so that a traditional switching value 0/1 representation method needs to be optimized, and the invention provides an attribute self-description dynamic data structure definition method.
By the proposed dynamic data structure, the modeling of the status signals such as the position of the primary device is carried out by taking the device as the object, and the status information of the device is expressed by an integer number (including 32 bits) of 4 bytes.
In order to be compatible with other remote signaling signals (hereinafter referred to as single-point single-phase signals) which still adopt one Bit to represent a specific state, the 17 th Bit and the 18 th Bit represent the attribute of the state, wherein the signal is a single-point single-phase signal, the signal is a single-Bit single-phase signal when the attribute is 0, the signal is a single-Bit single-phase signal when the attribute is 1, the signal is a double-Bit single-phase signal when the attribute is 2, the signal is a three-Bit single-phase signal when the attribute is 3, the specific data structure is shown in the following figures 2 and 3, and the like can be done by using a method of representing one state by three bits. In fig. 2, the lower 3 bits represent a, B, and C, respectively, and the 17 th and 18 th bits are attribute bits, and in fig. 3, the lower 6 bits represent a, B, and C, respectively, and the 17 th and 18 th bits are attribute bits.
In the process of implementing the semaphore simplification method described above, a correspondence relationship between the primary device and the secondary device needs to be established, and the measuring point association is not only a primary measuring point to a secondary point, but also a secondary measuring point to a secondary measuring point. In the specification, only the position signal of a certain circuit breaker is taken as an example, and actually, the monitoring output signal of one circuit breaker is up to ten types. The following description will take an example of a process for establishing a correspondence relationship:
optionally, the associating, according to the actual wiring condition of the simulated object, a remote signaling access point on the primary device with a remote signaling access point on the secondary device, and establishing a corresponding relationship and a phase between signals of the primary device and the secondary device, include:
the method comprises the steps that auxiliary nodes used for acquiring the on-off state of the monitoring breaker equipment are arranged in the breaker equipment, wherein the auxiliary nodes comprise a breaker normally-open auxiliary node 1 and a breaker normally-open auxiliary node 2;
eight remote signaling points from a remote signaling point 1 to a remote signaling point 8 are arranged in the secondary equipment, wherein,
the remote signaling point 1 and the remote signaling point 2 are respectively used for acquiring the closing position and the separating position signals of the circuit breaker,
the remote signaling point 3 and the remote signaling point 4 are respectively used for acquiring the signals of the corresponding position and the separate position of the circuit breaker A,
the remote signaling point 5 and the remote signaling point 6 are respectively used for acquiring the signals of the corresponding position and the separate position of the breaker B,
and the remote signaling point 7 and the remote signaling point 8 are respectively used for acquiring signals of the corresponding position and the separate position of the breaker C.
The establishing of the corresponding relationship between the signals of the primary equipment and the signals of the secondary equipment comprises the following steps:
the circuit breaker normally open auxiliary node 1 is connected with the remote signaling point 1, the circuit breaker normally open auxiliary node 2 is connected with the remote signaling point 2, the phase information is selected from three-phase total,
the circuit breaker normally open auxiliary node 1 is simultaneously connected with remote signaling points 3, 5 and 7, phase information respectively selects A phase, B phase and C phase,
the circuit breaker normally open auxiliary node 2 is connected with remote signaling point positions 4, 6 and 8 at the same time, and phase information respectively selects an A phase, a B phase and a C phase.
In the implementation, in order to accurately represent each phase of information of the device signal, the existing simulation signal description method represents each piece of information by using a single sampling point, and if a total signal is required to be represented, the information is represented by using a point, and then the value is assigned by using an and or equal relation, as shown in fig. 4 below. The advantage of adopting this kind of mode is that logic is realized simply, and the shortcoming is that the semaphore is big, and is possible for small system, but for regulation and control integration system, brings very big work load when the project is implemented. After the corresponding relationship between the primary device and the secondary device is established, it is necessary to obtain phase information of the primary device, where the phase information is a total of three phases, and as can be seen from the content of fig. 4, the total meaning of three phases indicates total joint position information of the primary device in fig. 4, including three phases, i.e., a phase B phase, and a phase C. And respectively receiving the three-phase total signals subjected to the combination and separation processing in the combined virtual signal by a remote signaling point 1 and a remote signaling point 2 in the secondary equipment.
A single-point multi-phase method is adopted, multi-phase signals are placed in a measuring point for representation by adopting a certain mapping relation, three-phase information is automatically contained in a single measuring point when a system is modeled, the simulation fineness is not lost, and the number of the measuring points of a database can be reduced to the minimum, as shown in figure 5. When the primary equipment access point is connected with the secondary equipment access point, the set phase difference domain is correlated, the traditional transformer substation primary and secondary equipment are connected through a secondary circuit, and some monitoring signals are connected to a signal acquisition device through the secondary circuit in a hard cable wiring mode and then sent into the integrated automation system.
However, in an actual system, the primary equipment mainly includes three phases, the number of signal openings of the acquisition device is relatively small, and in addition, monitoring personnel generally only need to monitor some important signals, so the signals of the primary equipment are usually selected or are connected to the signal acquisition device after being connected in series or in parallel at an auxiliary contact.
The remote signaling points used in the process comprise an opening point on the primary equipment and an opening point on the secondary equipment.
Comparing fig. 4 and fig. 5, it can be known that the phase splitting position signal and the total position signal acquisition simulation of one circuit breaker device are completed, and the existing simulation method needs to establish eight sampling points for the primary device and eight sampling points for the secondary device;
by adopting the method, only two sampling points are established for the primary equipment, and eight sampling points are established for the secondary equipment. In comprehensive comparison, the workload of primary equipment modeling is reduced 3/4, the total modeling amount is reduced 3/8, and the workload of comprehensive modeling can be reduced by more than half.
In particular, in actual field wiring, the switching-on position of the circuit breaker in fig. 4 is actually formed by connecting three points, namely, an a-phase normally-open auxiliary node 1, a B-phase normally-open auxiliary node 1 and a C-phase normally-open auxiliary node 1 in series; the circuit breaker opening position is actually formed by connecting three points of an A phase normally closed auxiliary node 1, a B phase normally closed auxiliary node 1 and a C phase normally closed auxiliary node 1 in parallel. For ease of comparison with fig. 5, the drawings are shown in parallel relationship. The series-parallel relationship shown in fig. 5 is realized by an internal algorithm of a program, and manual setting is not needed.
