Based on the background, the research on the application of the AGC automatic power generation control system in the unmanned direction of small hydropower stations is urgently needed by the nation and the industry, accords with the development trend of intelligent hydropower stations, has urgency in technical development, and has good social and economic benefits. The core content of the scheme is to construct an AGC system suitable for small hydropower stations, the core of the scheme is to construct an economic operation mathematical model of the small hydropower stations, determine an optimization criterion, an optimization algorithm and various constraint conditions in the automatic power generation control principle of the hydropower stations, analyze the power characteristics of the small hydropower stations and the power characteristics of power stations, determine AGC control strategies (a load control mode, a load distribution principle, a water level control strategy, a pressure control strategy, a locking and control abnormal strategy and the like), develop the design of AGC software of the small hydropower stations, regulate, control and monitor various data by combining a hydropower station control flow and operation control logic, optimize a system interface, and perform example calculation, optimization and application on the specific small hydropower stations.
According to one embodiment of the application, the control strategy of the automatic power generation control method of the small hydropower station is as follows:
load control mode: the system adopts a plant unit combined control mode, and automatically starts, stops and distributes loads according to priority.
Load distribution principle: 1. the system records the optimal efficiency unit and distributes load according to priority. 2. The system records the optimal efficiency area of the unit and enables the unit to operate in the optimal area as much as possible. 3. The number of actions is reduced as much as possible, frequent starting and stopping are avoided, and the service life is prolonged.
The water level control strategy is as follows: 1. when the actual water level is higher than the set value, the system automatically increases the active power. 2. And when the actual water level is lower than the set value but higher than the low water level, automatically reducing the active power. 3. And when the water level is reduced to be below the low water level, a stop command is issued, and all the generator sets are stopped.
The pressure control strategy is as follows: 1. the pressure is automatically controlled within the normal range according to the constant water level. 2. And if the pressure is smaller than the normal value, the load of the unit is reduced until the unit is stopped. 3. And after the pressure is recovered to be normal, starting a water level adjusting mode.
The lockout and control exception strategy is as follows: 1. the AGC system has three working conditions of operation, exit, locking and the like, the AGC unit has an abnormal control state besides the three states, and the abnormal control state comprises three working conditions of abnormal startup and shutdown, abnormal active control and abnormal reactive control. 2. The running and quitting states need manual operation. 3. When communication interruption, fault blocking signals, data value and quality abnormity, frequency abnormity, designated breaker position opening and manual self-defined blocking data point abnormity, the system enters a blocking state, and automatically shifts to operation after the data is recovered to be normal. 4. When the startup and shutdown control fails, the system enters a 'startup and shutdown control abnormal' working condition and locks the startup and shutdown operation; when the increase and decrease of active power are not converged, the system enters an 'active power control abnormal' working condition and locks active power control; when the increase and decrease of the reactive power are not converged, the system enters a working condition of abnormal reactive power control and closes the reactive power control. 5. The control of the abnormal state requires manual reset.
According to one embodiment of the application, the main control flow of the automatic power generation control method of the small hydropower station is as follows:
step one, data identification: the data recognition process is also called a data preprocessing process. The water level and pressure signals are the core judgment basis for the regulation of the AGC control system, and due to the interference of the field environment, the data quality of the water level and pressure signals is not high, and the problems of data volatility and data reliability exist, the system carries out algorithm pretreatment on the water level and pressure signals. The system caches n times of measurement results, and performs an abnormal data rejection filtering algorithm (rejection algorithm larger than 3 standard deviations) and a data smoothing algorithm (least square linear fitting algorithm) on n times of sampling values. The judgment basis of the system for control is that the system does not depend on the real-time value of single measurement any more, but carries out judgment according to the comprehensive result data after the calculation of n measurement samples.
Secondly, judging system locking and control abnormity: the AGC system has three working conditions of operation, exit, locking and the like, the AGC unit has an abnormal control state besides the three states, and the abnormal control state comprises three working conditions of abnormal startup and shutdown, abnormal active control and abnormal reactive control. The running and quitting states need manual operation. When communication interruption, fault blocking signals, data value and quality abnormity, frequency abnormity, designated breaker position opening and manual self-defined blocking data point abnormity, the system enters a blocking state, and automatically shifts to operation after the data is recovered to be normal. When the startup and shutdown control fails, the system enters a 'startup and shutdown control abnormal' working condition and locks the startup and shutdown operation; when the increase and decrease of active power are not converged, the system enters an 'active power control abnormal' working condition and locks active power control; when the increase and decrease of the reactive power are not converged, the system enters a working condition of abnormal reactive power control and closes the reactive power control. The control of the abnormal state requires manual reset.
Thirdly, judging a startup and shutdown process signal: when the system performs a power-on/off operation, the system enters a power-on/off process state, which typically takes 5 to 20 minutes, during which the system locks out all other control operations.
Fourthly, enabling and judging the adjustment function of the subsystem: the system has the functions of constant water level power regulation, startup and shutdown regulation, pressure control regulation, low water level shutdown and constant power factor regulation. Besides the constant water level adjusting function, if other adjusting functions need to be started, the function adjusting enabling fixed value needs to be set as 'input'. Controlling the constant water level: and tracking the water level change, increasing and decreasing active power operation is carried out on the unit, and the water level is kept relatively constant. The constant level adjustment subsystem only carries out increase and decrease active operation to carry out load distribution, and does not carry out startup and shutdown operation. If the on-off control is required, the on-off control subsystem function is required to be enabled. And (3) startup and shutdown control: when the started unit is fully started, the water level continuously exceeds the upper limit, and the un-started unit is started to generate power according to the priority; and when the generating power of the set is lower than the optimal water level lower limit after the set is started, the water level is continuously lower than the lower limit, and the set is closed according to the priority. And (3) pressure control: the pressure is automatically controlled within the normal range according to the constant water level. And if the pressure is smaller than the normal value, the load of the unit is reduced until the unit is stopped. And after the pressure is recovered to be normal, starting a water level adjusting mode. Controlling the dry water level: when the water level is lower than the set value of the dry water level, the shutdown operation is executed in sequence. Constant power factor control: the system automatically calculates the given reactive power value according to the set power factor setting value of the unit and keeps the power factor constant.
And fifthly, executing the regulation functions of all subsystems: and executing the subsystem regulation function according to the enabling condition of each regulation subsystem. The adjustment process and results are recorded in the system log. The success and failure verification is carried out on the adjustment result every time, and the abnormal operation is recorded when the startup and shutdown adjustment fails; the active and reactive mediation does not converge for a plurality of consecutive times (three times by default), and the abnormal operation is recorded. The unit control is locked when the operation is abnormal.
The quality control of the water level and pressure signals is realized, the water level and pressure signals are the core judgment basis for the regulation of an AGC control system, the problems of data volatility and data reliability exist due to the interference of the field environment and the low data quality of the water level and pressure signals, and the system carries out algorithm pretreatment on the water level and pressure signals.
