Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The remote dispatching method of the power plant can be applied to the application environment shown in FIG. 1. The application environment comprises a scheduling server 11, a power plant 12 to be scheduled; the dispatching server 11 is in communication connection with the power plant 12 to be dispatched. The scheduling server 11 acquires configuration information corresponding to the power plant 12 to be scheduled; the configuration information carries an operation mode identifier corresponding to the power plant 12 to be scheduled; the scheduling server 11 determines a starting capacity value of the power plant 12 to be scheduled from the configuration information according to the operation mode identifier; the dispatching server 11 performs error-proof check on the starting capacity value of the power plant 12 to be dispatched; if the startup capacity value of the power plant 12 to be scheduled passes the anti-error check, the scheduling server 11 generates a power plant scheduling instruction according to the startup capacity value, and sends the power plant scheduling instruction to the power plant 12 to be scheduled; the plant scheduling instructions are used to trigger the plant 12 to be scheduled to perform corresponding scheduling operations. The dispatch server 11 may be implemented by an independent server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, a remote dispatching method for a power plant is provided, which is described by taking the method as an example applied to the dispatching server 11 in fig. 1, and includes the following steps:
The configuration information can be obtained from a pre-established power plant operation model, and the power plant operation model can be understood as a database of power plant operation data; the power plant operation model can be established by adopting a three-level structure of region-power plant data, and the model and operation data information related to each power plant are stored; and according to the operation data information stored in the power plant operation model, the operation data can be created. Establishing a global configuration table according to the actual power plant operation condition, grasping the overall operation condition of a system formed by a plurality of power plants, and determining the information such as the size of the distributed electric energy load of each power plant according to the overall operation target of the system; each plant may have an operational mode such as a planning mode, a frequency modulation mode, and a manual mode.
Specifically, the scheduling server may set polling to collect configuration information from each power plant to be scheduled; the scheduling server may also set a schedule to periodically obtain configuration information of each power plant to be scheduled, and certainly, each power plant to be scheduled may also directly send the configuration information and the like to a pre-established power plant operation model; or actively sending configuration information or demand information to the scheduling server according to the plan, and the scheduling server allocates according to the acquired configuration information or demand information. The configuration information can carry not only an identifier corresponding to the operation mode, but also identification information of each power plant to be scheduled, such as a serial number, a current operator on duty, a contact way of the operator, an ip of the operator using the mobile device, and the like.
The scheduling server in the step analyzes and judges the operation condition of the power plant to be scheduled by acquiring the configuration information corresponding to the power plant to be scheduled, determines the currently adopted operation mode of the power plant to be scheduled through the operation mode identifier, and performs corresponding scheduling according to the operation mode, so that the scheduling efficiency of the power plant is improved.
And step 22, determining the starting capacity value of the power plant to be scheduled from the configuration information according to the operation mode identifier.
The starting capacity value is an operation capacity value which is comprehensively determined according to the current operation condition, the load condition, the plan condition and the like of the power plant to be scheduled and is required to be adjusted currently, and the power plant can adjust the capacity through the starting and stopping generator set to reach the allocated starting capacity value.
Specifically, the scheduling server obtains the starting capacity value calculation method corresponding to the operation mode identifier in different operation modes according to the operation mode identifier, obtains all parameters required by calculation from the configuration information, and comprehensively calculates to obtain the starting capacity value corresponding to the power plant to be scheduled. The determination of the starting capacity value can be obtained by comprehensively judging the configuration information of a plurality of power plants to be scheduled in the same period, for example, the starting capacity value of each power plant is determined simultaneously after the configuration information of the plurality of power plants in a certain area is obtained, so that the synchronous scheduling of the plurality of power plants in the certain area is realized, and the stability of the power load in the certain area is ensured; configuration information of a power plant can also be acquired, and the starting capacity value of the power plant is determined according to a global configuration table obtained by the acquired configuration information.
The difference scheduling of the power plant starting capacity value is realized through the operation mode identification, and meanwhile, the operation mode of each power plant can be adjusted according to actual conditions, so that the independence of each power plant is guaranteed, and the overall scheduling efficiency of the power plant is improved.
And step 23, performing error check on the starting capacity value of the power plant to be scheduled.
The starting capacity value is directly related to the starting and stopping of the units in the power plant to be scheduled within a period of time, so that the whole operation condition of the power plants in the region is normal, the starting capacity value of the power plant to be scheduled needs to be subjected to various limits, and the error check prevention is a series of conditions capable of limiting data. It should be noted that the check object for preventing error check may not only be the boot capacity value, but also be various parameters, instructions, identifications, and the like in the configuration information or outside the configuration information; the error check prevention may include the following items: 1) the newly calculated starting capacity is consistent with the effective capacity; 2) the last time of issuing the starting-up capacity is not equal to the effective capacity; 3) newly starting up the computer when the frequency of the region is greater than the upper limit; 4) the region frequency is less than the lower limit, so that the startup is reduced; 5) when the power generation time is less than a fixed value, newly starting up; 6) the total number of the power plants during startup is greater than the maximum number of the power plants allowed during scheduling; 7) the number of the power plants which are newly increased at one time and are started more than the maximum starting increment allowed by scheduling; 8) starting the power plant when the starting section of the power plant is out of limit; and shutting down the power plant when the shutdown section of the power plant is out of limit. When the error check prevention item 2) to the error check prevention item 8) are not satisfied, the dispatching server can send alarm information to corresponding personnel or terminal equipment and quit the remote dispatching function of the power plant, and when the error check prevention item 1) is not satisfied, the dispatching instruction of the power plant is not sent, but the remote dispatching function of the power plant is not quitted.
Specifically, the scheduling server checks the determined boot capacity value in combination with the anti-error check file or flow, and judges whether the boot capacity value, the scheduled object, the scheduled flow and the like meet the requirements; identifying the marks meeting the requirements as passing the anti-error check; and extracting the parts which do not meet the requirement of the anti-error check, generating alarm information and sending the alarm information to corresponding personnel or terminal equipment, or quitting the scheduling function of the power plant.
The dispatching server acquires an anti-error checking value from the anti-error checking module, compares the anti-error checking module value with a to-be-checked value in sequence, and determines that the to-be-checked value passes the check if a check result meets a preset threshold value; otherwise, determining that the value to be checked is wrong, generating corresponding early warning information according to the wrong value to be checked, and sending the corresponding early warning information to a corresponding early warning object.
The power-on capacity value of the power plant to be scheduled is subjected to error check by the scheduling server, so that all numerical values, sending objects and the like adopted by scheduling are reasonable, the normal operation of the power plant and the regional matching capability of each power plant are guaranteed, and the overall scheduling efficiency of the power plant is improved.
Specifically, the power plant scheduling instruction can also carry identification information and a public key of the power plant to be scheduled, and when the power plant to be scheduled acquires the power plant scheduling instruction, decryption processing is carried out according to the identification information and the public key; similarly, when the scheduling server generates the power plant scheduling instruction, the scheduling server may also encrypt the power plant scheduling instruction and the data information sent along with the power plant scheduling instruction. After the dispatching server generates a power plant dispatching instruction according to the starting capacity value, the starting instruction value of the power plant can be sent to other connected power plants, the other power plants can adjust the running conditions of the power plants after receiving the power plant dispatching instruction value, and the adjusted configuration information is sent to the dispatching server and the power plant running model for synchronous updating.
The scheduling server obtains a current plan value of the power plant to be scheduled, compares the current plan value with a starting capacity value, generates a power plant scheduling instruction according to a difference value of the starting capacity value and the current plan value, and sends the power plant scheduling instruction to the power plant to be scheduled. For example, the current planned value of the power plant a to be scheduled is 100, the adjustable capacity value is 300, the scheduling server determines that the gap load is 200 after obtaining the global configuration table from the power plant operation model, and then determines that the 200 loads of the gap are completed by the power plant a to be scheduled, and the power plant scheduling instruction received by the power plant a to be scheduled is an instruction for increasing 200 loads.
The scheduling server generates a power plant scheduling instruction according to the starting capacity value and sends the power plant scheduling instruction to the power plant to be scheduled, so that scheduling of the power plant to be scheduled is achieved, and overall scheduling efficiency of the power plant is improved.
The remote scheduling method of the power plant comprises the following steps: acquiring configuration information corresponding to a power plant to be scheduled; the configuration information carries an operation mode identifier corresponding to the power plant to be scheduled; according to the operation mode identification, determining a starting capacity value of the power plant to be scheduled from the configuration information; performing error check on a starting capacity value of a power plant to be scheduled; if the power plant to be scheduled passes the anti-error check of the starting capacity value, generating a power plant scheduling instruction according to the starting capacity value, and sending the power plant scheduling instruction to the power plant to be scheduled; the power plant scheduling instruction is used for triggering a power plant to be scheduled to execute corresponding scheduling operation. The operation mode of confirming the power plant in the configuration information that this application was followed to treat the dispatch power plant and is corresponded, determines the start capacity value that corresponds with the power plant according to the operation mode, generates the scheduling instruction of power plant according to the start capacity value through preventing mistake inspection, has realized the long-range unified dispatch to the power plant, has improved the dispatch efficiency to the power plant.
In one embodiment, as shown in fig. 3, before obtaining the configuration information corresponding to the power plant to be scheduled, step 21 further includes:
The preset updating time table records the updating time of the operation data information of the power plant to be scheduled, and the scheduling server can actively acquire the operation data information from the power plant to be scheduled after a certain recorded time. In a three-level structure of region-power plant data, region layer information comprises region closed loop, region open loop and region frequency; the power plant information comprises whether the power plant is started, a control mode, a manual mode set value, the maximum startup allowed number of scheduling, the maximum startup increment allowed number of scheduling, a calculated startup capacity value (remote adjustment value), a last startup capacity value (remote adjustment value), a capacity value to be issued (remote adjustment value), single machine capacity and the like; the power plant data comprises section data, planning value data, effective capacity and electricity generating hours. The global table comprises a total function start-stop identification and the like.
Specifically, the scheduling server may obtain operation data information of the power plant to be scheduled according to the update schedule, or obtain monitored operation data information of the power plant to be scheduled from a preset power plant operation model; of course, the preset power plant operation model can also obtain the operation data information of the power plant to be scheduled according to the preset update schedule. The updated operational data may include regional frequency, projected values, profile data, effective capacity, hours that can generate electricity. Wherein, the Data of the area frequency, the effective capacity And the power generation hour are synchronized from an SCADA (Supervisory Control And Data Acquisition, Data Acquisition And monitoring Control system), And the synchronization period is 1 s; synchronizing the section data from the section monitoring system with a synchronization period of 1 s; the planned value data is synchronized from the startup capacity planned value modules of each power plant, and when the startup capacity planned value changes, synchronization is performed immediately. The power plant operation model can detect the configuration information and perform early warning according to the data transaction condition of the configuration information, for example, 1) when a planned value is 15min away in the future, three machines are started and a warning is given; and within 45min in the future, alarming and exiting the automatic plant start-stop function. 2) When the planned value is started and stopped or stopped and started within 30min beyond 60min in the future, alarming; and within 60min in the future, alarming and exiting the automatic plant start-stop function. 3) And when the planned value within 15min in the future is modified, alarming and exiting the automatic plant start-stop function. 4) When the frequency is higher or lower, the out-of-limit flag is set.
The real-time performance of the operation data information of the power plant to be scheduled is guaranteed through the preset updating time table; the updated configuration information is monitored through the power plant operation model, the abnormal condition of each power plant can be determined at the first time, and the scheduling efficiency of the power plants is improved.
In one embodiment, step 32, after inputting the operation data information into the preset plant operation model, further comprises: if early warning information sent by the power plant operation model is received, removing the corresponding identification information of the power plant to be scheduled from the identification information list of the power plant to be scheduled according to the early warning information; the identification information list of the power plants to be scheduled stores identification information of a plurality of power plants to be scheduled.
Specifically, the scheduling server determines the early warning level of the power plant to be scheduled according to the received early warning information, for example, the low-level early warning can forward the early warning information to a worker for processing, the high-level urgent early warning information can inform relevant workers of processing and simultaneously move the identification information of the power plant to be scheduled out of the list of the identification information of the power plant to be scheduled, and the power plant to be scheduled, which is not in the list, cannot perform remote scheduling operation.
According to the embodiment, the abnormal reason of the power plant to be scheduled is determined through analysis of the early warning information, different maintenance measures are taken according to the abnormal reason, and stable operation of the power plant is guaranteed.
In one embodiment, step 22, as shown in fig. 4, determining a startup capacity value of the power plant to be scheduled from the configuration information according to the operation mode identifier includes:
and 43, if the operation mode identification is detected to be the manual mode identification, determining the manual set value as the starting capacity value of the power plant to be scheduled.
The frequency is a basic index of power grid operation, the guarantee of the frequency quality is one of main targets of power grid dispatching operation work, and whether a power grid frequency modulation mode reasonably and directly relates to the frequency quality is judged. The frequency modulation mode is specified by the master tuner according to the operation requirement of the power grid, and the frequency deviation coefficient of each region is specified by the master tuner according to the primary frequency modulation input condition, the load regulation characteristic and the like of each region; the existing frequency modulation modes include primary frequency modulation, secondary frequency modulation and the like. The scheduled frequency modulation can be dynamic frequency modulation according to a scheduled value, namely, according to boot capacity values distributed at different moments, so that a scheduled task is achieved as a frequency modulation target. The manual mode is adjusted according to the value set by the corresponding person. Multiple data used for calculating the boot capacity can be acquired from the plan value information in the configuration information, specifically, current _ scheduled is a current plan value, namely a first plan value, next _ scheduled is a next 5min plan value, namely a second plan value, set _ value is a value for issuing a boot remote adjustment value, namely the boot capacity value, unit is the stand-alone capacity, max _ open is the maximum number of boot allowed in scheduling, and N is the current number of boot devices.
Specifically, the frequency modulation server obtains an operation mode identifier of the power plant to be frequency modulated, and can determine the current operation mode of the power plant according to the operation mode identifier, wherein the current operation mode can be a plan mode, a manual mode and a frequency modulation mode. Of course, after the mode is changed or periodically, each power plant sends information carrying the operation mode identifier to the scheduling server, so as to ensure that the system determines the starting capacity value of the power plant to be scheduled according to the algorithm corresponding to the operation mode. The power plant is in manual mode: set _ value equals the manual mode set point.
The frequency modulation server determines a corresponding method for determining the starting capacity value through the operation mode identifier, so that the accuracy of the frequency modulation value of each power plant is ensured.
In one embodiment, in step 41, if it is detected that the operation mode identifier is the planning mode identifier, determining a starting capacity value of the power plant to be scheduled according to the first planning value, the second planning value, the single machine capacity value, and the current starting number includes: if the first plan value is equal to the second plan value, determining the first plan value as a starting capacity value of the power plant to be scheduled; and if the second plan value is not equal to the first plan value, determining the current starting capacity value of the power plant to be scheduled according to the first plan value and the single machine capacity value, and determining the starting capacity value of the power plant to be scheduled according to the current starting capacity value and the single machine capacity value.
Specifically, while the plant is in planning mode:
1) when current _ scheduled equals next _ scheduled: set _ value equals current _ scheduled;
2) when next _ scheduled is greater than current _ scheduled: then N equals (current _ scheduled-100)/unit rounded down, set _ value equals (N +1) × unit;
3) when next _ scheduled is less than current _ scheduled: set _ value equals zero if current _ scheduled/unit is less than 0.25, otherwise N equals (current _ scheduled/unit) rounded down and set _ value equals (N +1) × unit.
In one embodiment, in step 42, if it is detected that the operation mode identifier is the fm mode identifier, determining the startup capacity value of the power plant to be scheduled according to the first plan value, the second plan value, the single machine capacity value, the maximum startup number, and the current startup number, includes:
if the first plan value is equal to the second plan value and the second plan value is smaller than the product of the maximum starting number and the single machine capacity value, determining the first plan value as the starting capacity value of the power plant to be scheduled;
if the first plan value is equal to the second plan value and the first plan value is larger than or equal to the product of the maximum starting number and the single machine capacity value, determining the product of the maximum starting number and the single machine capacity value as the starting capacity value of the power plant to be scheduled;
if the first plan value is not equal to the second plan value, determining the number of current startup units according to the first plan value and the single machine capacity value;
when the current starting number is smaller than the maximum starting number, determining a starting capacity value of the power plant to be scheduled according to the current starting number and the single machine capacity value;
and when the current starting number is larger than or equal to the maximum starting number, determining the product of the maximum starting number and the single machine capacity value as the starting capacity value of the power plant to be scheduled.
Specifically, when the plant is in frequency modulation mode:
1) when current _ scheduled equals next _ scheduled: when current _ scheduled is less than max _ open _ unit, set _ value is equal to current _ scheduled, and when current _ scheduled is greater than or equal to max _ open _ unit, set _ value is equal to max _ open _ unit;
2) when next _ scheduled is not equal to current _ scheduled: n is equal to (current _ scheduled/(unit-20)) rounded down, when N is less than max _ open, set _ value is equal to (N +1) unit, otherwise set _ value is equal to max _ open unit.
In one embodiment, step 24, after sending the plant scheduling command to the plant to be scheduled, further includes: receiving a scheduling operation result returned by the power plant to be scheduled; and updating the configuration information corresponding to the power plant to be scheduled and the remote scheduling log according to the scheduling operation result.
Specifically, the power plant to be scheduled may perform corresponding scheduling operations according to the received scheduling instruction, such as turning on a generator set or turning off a running generator set. After the power plants to be scheduled execute the instruction, the execution result is sent back to the scheduling server, the scheduling server updates the configuration information corresponding to each power plant according to the received information, updates the global configuration table, and simultaneously stores all information related to the scheduling into a remote scheduling log, so that problems occurring at a later period can be consulted and processed in time, or logic error correction is performed uniformly, and a scheduling algorithm is improved.
According to the embodiment, the configuration information and the remote scheduling log are updated by acquiring the scheduling operation result returned by the power plant to be scheduled, so that the historical consultability of the data is ensured.
