Description

Technical Field

[0001] The present invention belongs to the technical field of emergency control of hydropower stations, and in particular relates to an emergency control method, device and computer program product of a run-of-river hydropower station. Background Art

[0002] In the actual production and operation process of the hydropower station, in order to maintain the basic operation safety of the hydropower station, it is often necessary to carry out emergency control of the run-of-river hydropower station. Most of the existing emergency control systems of run-of-river hydropower stations adopt a monitoring and response mechanism based on water level and flow. The emergency control system usually includes a water level monitoring device, a flow control valve and a simple logic control unit, which is used to automatically adjust the opening of the control valve when abnormal water level or flow is detected to maintain the basic operation safety of the hydropower station.

[0003] However, traditional emergency control methods mostly rely on manually set thresholds for triggering, and the response strategy is relatively simple. At the same time, there is a lack of a systematic cyclic response mechanism. Emergency control systems can often only perform simple opening adjustments, and most emergency control systems operate independently and lack linkage with upstream water conservancy facilities, resulting in a long response time in emergencies. It is difficult to respond quickly to complex and changeable emergency scenarios, and it is impossible to perform fine-grained regulation, which limits the regulation capacity and operating efficiency of the hydropower station.

[0004] Therefore, how to provide an effective solution to achieve real-time and accurate emergency control of run-of-river hydropower stations has become a difficult problem to be solved in the prior art. Summary of the invention

[0086] In an embodiment of the present application, a first threshold interval, a second threshold interval, and a third threshold interval are pre-set for evaluating the emergency level corresponding to the run-of-river hydropower station. The threshold in the first threshold interval is smaller than the threshold in the second threshold interval, and the threshold in the second threshold interval is smaller than the threshold in the third threshold interval.

[0087] If the comprehensive emergency score is in the first threshold interval, the emergency level corresponding to the run-of-river hydropower station is determined to be the first emergency level; if the comprehensive emergency score is in the second threshold interval, the emergency level corresponding to the run-of-river hydropower station is determined to be the second emergency level; if the comprehensive emergency score is in the third threshold interval, the emergency level corresponding to the run-of-river hydropower station is determined to be the third emergency level.

[0088] In one or more embodiments, when the emergency level corresponding to the run-of-river hydropower station is the first emergency level, corresponding emergency handling measures are taken based on the emergency level corresponding to the run-of-river hydropower station, which may include but are not limited to the following steps S201-S206.

[0089] Step S201: Determine whether the first power circuit and the second power circuit are failed based on the electrical state parameter matrix.

[0090] In the embodiment of the present application, it can be determined whether the first power circuit and the second power circuit are failed based on the sampled voltage and sampled current of the first and second power circuits in the electrical state parameter matrix at the current sampling moment.

[0091] Step S202: If one of the first power circuit and the second power circuit loses power, the power circuit that loses power is supplied with power through the remaining power circuit.

[0092] Step S203: Based on the latest transmission line status matrix of the run-of-river hydropower station, determine whether the transmission line of the generator set of the run-of-river hydropower station is interrupted.

[0093] In the embodiment of the present application, it is possible to determine whether the output line of the generator set of the run-of-river hydropower station is interrupted based on the active power and reactive power at the sampling moment in the output line state matrix.

[0094] Step S204: If the output line of the generator set of the run-of-river hydropower station is not interrupted, the diesel generator is started to supply power to the power circuit that has lost power.

[0095] Step S205: If the outgoing line of the generator set of the run-of-river hydropower station is interrupted, the first power circuit and the second power circuit are powered by an external grid power supply.

[0096] Step S206: If both the first power circuit and the second power circuit lose power, start the diesel generator to supply power to the emergency control system of the run-of-river hydropower station.

[0097] When the emergency level corresponding to the run-of-river hydropower station is the second emergency level, corresponding emergency handling measures are taken based on the emergency level corresponding to the run-of-river hydropower station, which may include but are not limited to the following steps S301-S303.

[0098] Step S301. Based on the water level state matrix of the regional reservoir, the inflow and outflow flow state matrix and the current state of the flood discharge gate, determine whether the flood discharge gate meets the gate opening adjustment triggering condition.

[0099] Specifically, it can be determined whether the determinant value corresponding to the district reservoir water level status matrix reaches the second preset threshold, whether the determinant value corresponding to the inlet and outlet flow status matrix reaches the third preset threshold, and whether the ratio of the outbound flow to the inbound flow in the inlet and outlet flow status matrix is ​​lower than the fourth preset threshold.

[0100] If the determinant value corresponding to the zone reservoir water level status matrix reaches the second preset threshold, the determinant value corresponding to the inlet and outlet flow status matrix reaches the third preset threshold, the ratio of the outflow flow to the inflow flow in the inlet and outlet flow status matrix is ​​lower than the fourth preset threshold and the current state of the flood discharge gate is an unmaintained state, then it is determined that the flood discharge gate meets the gate opening adjustment trigger condition.

[0101] The fourth preset threshold is less than 1, and for example the value of the fourth preset threshold may be 0.6.

[0102] Step S302: If the flood discharge gate meets the gate opening adjustment triggering condition, the flood discharge gate opening is adjusted so that the determinant value corresponding to the latest flood discharge gate state matrix of the run-of-river hydropower station reaches a first preset threshold.

[0103] Step S303: If the flood discharge gate does not meet the gate opening adjustment triggering conditions, an alarm signal is issued.

[0104] When the emergency level corresponding to the run-of-river hydropower station is the third emergency level, corresponding emergency handling measures are taken based on the emergency level corresponding to the run-of-river hydropower station, which may include but are not limited to the following steps S401-S402.

[0105] Step S401. If the current state of the flood discharge gate is an unmaintained state, the opening of the flood discharge gate is adjusted so that the determinant value corresponding to the latest flood discharge gate state matrix of the run-of-river hydropower station reaches a fifth preset threshold.

[0106] Step S402: If the current state of the flood discharge gate is a maintenance state, an alarm signal is issued.
