The system also comprises a database in communication connection with the host, wherein the host stores the received data backup in the database.
The two main machines are in a double-main-machine mode and are mutually standby, so that the power generation capacity acquisition system of the step power plant can normally operate in a main machine fault state. The host is used for receiving information such as the power generation capacity of the step power plant, the state of the power generation equipment and the like, and can perform relevant calculation, application, prompt and the like.
The power plant side power generation capacity reporting device is arranged inside the step power plant, and the sent information comprises the power generation capacity of the power plant, the start-stop sequence of a power generating set of the power plant, the defect state of power generating equipment and the special operation mode of the power generating set. Meanwhile, the device has a prompt function, and when a power plant worker does not timely finish reporting work or reporting data are abnormal, the device sends out a prompt to prompt the worker to timely finish corresponding work.
The power generation information receiving device of the power grid system is arranged in the centralized control center, and the received data comprise a step power plant power generation plan, a power grid system overhaul condition, a power grid system line load condition and a power grid line voltage and frequency condition of a step power plant outgoing line. The specific scheme is as follows.
Regarding a step power plant generation schedule: the power grid system can generate a power generation plan of a power plant belonging to the power grid jurisdiction, after the system acquires the power generation plan of the step power plant, the running mode of the step power plant generator set is arranged according to the power generation plan condition, and other related works (works such as defect treatment of power generation equipment) are arranged according to the power generation plan condition.
Regarding the grid system overhaul condition (influencing the power generation operation mode of the step power plant): the power grid system overhaul has a large influence on the power generation operation mode of the step power plant, sometimes the power grid system line overhaul is carried out, the large-load operation of the power generation unit of the step power plant is required to meet the power utilization requirement of the power grid, sometimes the operation of new equipment of the power grid system is required to generate power according to the requirement, or the power generation unit of the step power plant is required to carry out frequency modulation and the like when the power grid system fails. The system can give a prompt after acquiring the power grid overhaul information, and prompts a worker to be ready in time.
Regarding grid system line load conditions: the load condition of the power grid system line affects the operation load of the step power plant, when the line is overloaded, the operation load of the step power plant can be limited, especially when the reservoir capacity is vacated in the flood season or the flood season, the condition that the reservoir water level of the step power plant is higher can be caused by limiting the load of the step power plant, the load condition of the power grid system line is acquired in time, and the load preparation of the step power plant is actively adjusted.
Regarding the voltage and frequency conditions of the power grid line connected with the step power plant outgoing line: the voltage, frequency and other parameters of the line connected with the step power plant outgoing line have great influence on the power generation operation of the step power plant, and the step power generation unit is required to regulate the voltage when the line voltage is low. The information is acquired, and the actual power generation running condition of the step power plant is timely acquired and is used as a reference basis for power generation running, power generation planning and other works.
The data received by the step power plant generator set operation mode receiving device comprises the state of the generator set, the maximum output force, the minimum output force and the vibration interval of the generator set, the health level of the generator set, the priority start-stop sequence of the generator set and the special operation requirement of the generator set. The specific contents are as follows.
Genset status (overhauling, standby, defect): the state of the generator set mainly judges whether the generator set can normally run in a grid connection mode, the maintenance state refers to the fact that the generator set cannot generate electricity in maintenance, the standby state refers to the fact that the generator set can generate electricity at any time when in standby, and the defect state refers to the fact that the generator set can generate electricity but rated output cannot be generated or the generator set can stop at any time when the generator set has defects.
Maximum output force, minimum output force and vibration interval of generator set: the reservoir water level of the step power plant can change, and when the reservoir water level is low, the maximum output of the generator set is lower than the rated output when the operating water head of the generator set is lower than the rated water head, namely the maximum output is lower than the output on the nameplate of the generator. The vibration interval of the generator set is a load interval which cannot be operated. The minimum output of the generator set refers to the minimum load that can be operated. The maximum output force, the minimum output force and the vibration interval of the generator set are all used for the working of the step power plant power generation planning.
Health level of the generator set: the step power plant fills up the healthy level of the generator set of the step power plant according to actual conditions, and the step power plant centralized control center determines the healthy level of the generator set according to the information such as the healthy level of the generator set, the actual running conditions of the generator set and the generating equipment, and the healthy level can be designed to be excellent, good and general three conditions, and can also be designed into various healthy level modes according to working requirements.
Priority start-stop sequence of generator set: when the step power plant power generation capacity reporting is carried out, the step power plant carries out the start-stop sequence reporting of the generator sets, step power plant staff determines the start-stop sequence of the step power plant generator sets according to the conditions of the power plant generator sets such as health level, operation requirement, defect elimination work arrangement, maintenance work arrangement and the like, and centralized control center staff carries out the start-stop of the step power plant generator sets according to the start-stop sequence.
Special operation requirements of the generator set: because of equipment defects or other reasons, a generator set has some operation requirements when generating electricity, for example, a certain generator set cannot frequently adjust load (preferably, the generator set operates with fixed load), a certain generator set can only operate in a large load interval, and a certain generator set needs to be stopped in a special operation mode such as a certain time period. After the centralized control center staff receives the information, the special operation mode arrangement is carried out according to the actual power generation requirement.
Furthermore, the host is also connected with an auditing device, the auditing device is provided with an automatic auditing part and a manual auditing part, and the auditing result is transmitted to the host, and the data inspected by the auditing device comprises the power generation capacity information reported by the step power plant, whether the power grid system information is perfect or not, and the power generation plan of the step power plant is matched with the power generation capacity of the step power plant. Specifically, the following parts are included.
Checking power generation capability information reported by a step power plant: after all the step power plants report the power generation capacity information, centralized control center staff checks the step power plant power generation information, mainly checks whether the filling information is perfect or not, if not, the step power plants can be informed of being modified or being modified by themselves after inquiry. After the auditing is finished, a step power plant power generation capacity situation meter is formed and is used for working such as later power generation planning, power generation operation mode arrangement and the like.
Checking whether the acquisition of the power grid system information is perfect: checking whether the related information of the power grid system is complete and perfect, wherein the power generation plan of the step power plant is required to be acquired, otherwise, the running mode of the step power plant for starting and stopping can not be arranged, and other information can effectively assist the step power plant to develop the optimal scheduling work and needs to be perfect as much as possible.
The step power plant power generation plan is matched with the step power plant power generation capacity: the step power generation capacity declaration has the important function of ensuring that the power generation plan of the step power plant is reasonably executable, and the system can be matched with the formed step power generation capacity situation meter after acquiring the power generation plan of the step power plant of the power grid system, so that the power generation plan can be executed after the matching, and the power generation plan needs to be processed in time when the power generation plan cannot be executed.
Step power plant power generation capacity condition table derives: the power generation capacity of the cascade power plant is required for each work development of the cascade power plant centralized control center in the river basin, and after the centralized control center staff finishes the work, the table is required to be exported and is applied to the optimization scheduling work of the cascade power plant in the river basin.
The database is used for storing data such as a step power plant power generation capacity meter formed after the step power plant power generation capacity is audited by the centralized control center and reported by the step power plant. The database stores all data related to the step power plant power generation capacity declaration for analysis and calculation.
In a further aspect, the operator station includes two stations disposed in parallel so as to be disposed at different positions of the centralized control center. The functions of the two operator stations are completely the same, namely the human-computer interaction device, all the operation and system operation settings of the personnel in the centralized control center of the river basin step power plant are operated on the device, and the operator stations can perform related operation after logging in, so that the safety of the system is ensured.
With respect to the monitoring system, an interface is reserved between the host and the monitoring system, so that the host can call relevant operation data of the centralized control center monitoring system for collecting, calculating and analyzing the power generation capacity of the step power plant, and meanwhile, the host can upload the data of the power generation capacity condition, the power generation equipment state, the power generation equipment health level and the like of the step power plant to the monitoring system for the step power plant to dispatch, operate, manage and use the monitoring system.
