Description

Technical Field

[0002] Bulb-type hydroelectric generator sets have developed rapidly in China in recent years due to their high efficiency, low investment, and fast construction. In recent years, the governor power mode is often used for load regulation of bulb-type hydroelectric generator sets. It has the characteristics of fast and convenient regulation, and is especially suitable for hydropower plants that have achieved remote centralized control operation. The bulb-type hydro-turbine generator set has a small moment of inertia and a low operating head. It is generally a daily or weekly regulating reservoir with a small reservoir capacity. In this mode, there is a large range of head changes and frequent adjustments when the unit is running, especially during the flood season when the floodgates are opened for flood discharge due to a large inflow of water, and the water level changes more frequently. In addition, this type of machine has a large flow rate, a large water flow time constant, and the blades of the double-regulation unit follow the guide vanes. The stability is poor during the transition process of frequent response to load regulation. Secondly, when the head changes frequently, the guide vanes also need to be adjusted frequently to maintain the load, and the blades follow the guide vanes relatively slowly, which can easily lead to load fluctuations. The associated governor oil pump will also have a greatly shortened life after frequent loading, seriously affecting the safe and stable operation of the bulb-type hydro-turbine generator set.

[0020] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0021] The present application proposes a method and device for load stabilization regulation of a bulb-type hydro-turbine generator set, which obtains the real-time power generation of the bulb-type hydro-turbine generator set, the preset power generation value of the bulb-type hydro-turbine generator set, and the water head signal corresponding to the bulb-type hydro-turbine generator set; determines the difference between the real-time power generation of the bulb-type hydro-turbine generator set and the preset power generation value of the bulb-type hydro-turbine generator set; and adjusts the opening of the guide vanes and blades of the generator set based on the difference and the water head signal corresponding to the bulb-type hydro-turbine generator set until the real-time power generation of the bulb-type hydro-turbine generator set is equal to the preset power generation value of the bulb-type hydro-turbine generator set. The technical solution provided by the present invention adjusts the load of the bulb-type hydro-turbine generator set to ensure safe and stable operation of the bulb-type hydro-turbine generator set.

[0022] The following describes a method and device for load stabilization regulation of a bulb-type cross-flow hydro-turbine generator set according to an embodiment of the present application with reference to the accompanying drawings.

[0023] Example 1

[0024] Figure 1 A flow chart of a method for load stabilization regulation of a bulb-type hydro-turbine generator set provided in an embodiment of the present disclosure is shown in FIG. Figure 1 As shown, the method includes:

[0025] Step 1: obtaining the real-time power generation of the bulb-type hydro-turbine generator set, the preset power generation set value of the bulb-type hydro-turbine generator set, and the water head signal corresponding to the bulb-type hydro-turbine generator set;

[0026] It should be noted that the preset value of the power generation power of the bulb-type cross-flow turbine generator set is set by the central control room personnel within a normal range according to the requirements of the dispatching agency.

[0027] It should be noted that before determining the difference between the real-time power generation of the bulb-type hydro-turbine generator set and the preset power generation value of the bulb-type hydro-turbine generator set, it is necessary to judge whether the real-time power generation of the bulb-type hydro-turbine generator set is greater than the preset power value and is not a primary frequency modulation action. If so, the opening of the guide vanes and blades of the generator set will not be adjusted, and the opening of the guide vanes and blades of the generator set in the previous week will be maintained; wherein, the preset power value can be 102% of the rated power, and when the frequency value of the power grid system is greater than or equal to 49.95HZ and less than or equal to 50.05HZ, it is a non-primary frequency modulation action.

[0028] Step 2: determining the difference between the real-time power generation of the bulb-type hydro-turbine generator set and a preset power generation value of the bulb-type hydro-turbine generator set;

[0029] It should be noted that, after determining the difference between the real-time power generation power of the bulb-type hydro-turbine generator set and the preset power generation power given value of the bulb-type hydro-turbine generator set, the following steps are further performed:

[0030] Determine whether the generator set has power fluctuation. If so, adjust the opening of the guide vanes and blades of the generator set based on the rated power generation value of the bulb-type cross-flow turbine generator set. Otherwise, make adjustments as in step 3.

[0031] For example, when the regulator refresh cycle in the power plant is 10ms, the difference between the current real-time power generation power of the bulb-type cross-flow turbine generator set and the real-time power value after 100ms is greater than 0, and the difference between the real-time power value after 100ms and the real-time power value after 200ms is less than 0, that is, the real-time power value jumps back and forth, which is judged as power fluctuation, or the power collected by the speed regulator system electric control cabinet regulator in the power plant fluctuates, which is judged as power fluctuation.

[0032] Specifically, adjusting the opening of the guide vanes and blades of the bulb-type hydro-turbine generator set based on the rated power generation value of the bulb-type hydro-turbine generator set includes:

[0033] When the difference between the real-time power generation of the bulb-type hydro-turbine generator set and the preset power generation set value of the bulb-type hydro-turbine generator set is greater than the first power preset value, the opening of the guide vanes and the blades of the generator set is adjusted. If the generator set is still in a power fluctuation state after the adjustment time is greater than the first preset period, the adjustment is exited to maintain the guide vane opening of the current generating point unit, and then the opening reference value of the blade corresponding to the generator set is determined based on the guide vane opening of the current generating point unit, the head signal corresponding to the bulb-type hydro-turbine generator set and the preset synergy characteristic curve, and the blade corresponding to the generator set is adjusted based on the opening reference value. After the adjustment is completed, the adjustment is exited until the preset power generation set value of the bulb-type hydro-turbine generator set changes. The first power preset value may be 1% of the rated power, and the first preset period may be 90 seconds.

[0034] When the difference between the real-time power generation power of the bulb-type hydro-turbine generator set and the preset power generation power given value of the bulb-type hydro-turbine generator set is greater than the second power preset value and less than or equal to the first power preset value, the opening of the guide vanes and the blades of the generator set is adjusted. If the generator set is still in a power fluctuation state after the adjustment time is greater than the second preset period, the adjustment is exited and the opening of the guide vanes of the current generator set is maintained. Then, based on the guide vane opening of the current generating point unit, the head signal corresponding to the bulb-type hydro-turbine generator set and the preset synergy characteristic curve, the opening reference value of the blades corresponding to the generator set is determined, and the blades corresponding to the generator set are adjusted based on the opening reference value. After the adjustment is completed, the adjustment is exited until the preset power generation given value of the bulb-type hydro-turbine generator set changes.

[0035] The second preset power value may be 0.1% of the rated power, and the second preset time period may be 30 seconds.

[0036] It should be noted that, based on the guide vane opening of the current generating unit, the head signal corresponding to the bulb-type hydro-turbine generator set and the preset cooperative characteristic curve, the opening reference value of the blade corresponding to the generator set is determined, and the blade corresponding to the generator set is adjusted based on the opening reference value, including:

[0037] Processing the water head signal corresponding to the bulb-type hydro-turbine generator set to obtain a water head sampling value after interference is removed;

[0038] The preset cooperative characteristic curve is used to calculate the opening reference value of the guide vane and the opening reference value of the blade corresponding to the generator set under the head sampling value after interference is removed, and the blade corresponding to the generator set is adjusted based on the opening reference value.

[0039] Step 3: Based on the difference and the head signal corresponding to the bulb-type hydro-turbine generator set, the opening of the guide vanes and blades of the generator set is adjusted until the real-time power generation of the bulb-type hydro-turbine generator set is equal to the preset power generation given value of the bulb-type hydro-turbine generator set.

[0040] In the embodiment of the present disclosure, the opening of the guide vanes and blades of the generator set is adjusted based on the difference and the water head signal corresponding to the bulb-type hydro-turbine generator set until the real-time power generation of the bulb-type hydro-turbine generator set is equal to the preset power generation given value of the bulb-type hydro-turbine generator set, such as Figure 2 As shown, including:

[0041] Step F1: if the generator set does not experience power fluctuation, determine the guide vane opening reference value based on the difference, and then adjust the current guide vane opening of the generator set to the reference value; and process the water head signal corresponding to the bulb-type hydro-turbine generator set to obtain a water head sampling value after interference removal;

[0042] Among them, the water head signal corresponding to the bulb-type cross-flow turbine generator set is processed to obtain the water head sampling value after interference is removed. The water head signal is collected and input into the analog input channel of the regulator for A / D conversion calculation, and then processed by the ramp function module of the regulator, and finally the water head sampling value after interference is obtained, thereby ensuring that the water head sampling value does not cause the blade control value calculated by the regulator coordination module to change frequently due to signal interference, wherein the processing of the ramp function module of the regulator includes using the ramp function processing to make the water head signal change slowly with the set slope.

[0043] Step F2: using a preset synergy characteristic curve to calculate the opening reference value of the guide vane and the opening reference value of the blade corresponding to the generator set under the head sampling value after interference is removed, and adjusting the blade corresponding to the generator set based on the opening reference value;

[0044] Step F3: When the real-time power generation of the generator set is equal to the preset power generation set value of the bulb-type hydro-turbine generator set, the load regulation ends; otherwise, the power generation set value of the bulb-type hydro-turbine generator set is newly set, and the process returns to step F1.

[0045] The specific implementation method of the above-mentioned bulb tubular turbine generator set load stabilization regulation method can be as follows: Figure 3 shown.

[0046] Combined with the above-mentioned bulb tubular turbine generator set load stabilization regulation method, its application is illustrated by example:

[0047] Firstly, the real-time power generation of the bulb-type hydro-turbine generator set, the preset power generation value of the bulb-type hydro-turbine generator set and the water head signal corresponding to the bulb-type hydro-turbine generator set are obtained, and it is determined whether the real-time power generation of the bulb-type hydro-turbine generator set is greater than the preset power value and is not a primary frequency modulation action. If so, the opening of the guide vanes and the blades of the generator set is not adjusted, the opening of the guide vanes and the blades of the generator set in the previous week is maintained, or power generation is terminated;

[0048] Then, the difference between the real-time power generation of the bulb-type hydro-turbine generator set and the preset power generation value of the bulb-type hydro-turbine generator set is determined, and it is judged whether the generator set has power fluctuation. If so, the opening of the guide vane and the blade of the generator set is adjusted based on the rated power generation value of the bulb-type hydro-turbine generator set; otherwise, the opening of the guide vane and the blade of the generator set is adjusted based on the difference and the water head signal corresponding to the bulb-type hydro-turbine generator set;

[0049] Finally, based on the difference and the head signal corresponding to the bulb-type hydro-turbine generator set, the opening of the guide vanes and blades of the generator set is adjusted until the real-time power generation power of the bulb-type hydro-turbine generator set is equal to the preset power generation power given value of the bulb-type hydro-turbine generator set.

[0050] To sum up, the embodiment of the present disclosure provides a method for stabilizing the load of a bulb-type hydro-turbine generator set. By adjusting the load of the bulb-type hydro-turbine generator set, the bulb-type hydro-turbine generator set can operate safely and stably, and can also maintain a stable and slowly changing operating water head, thereby eliminating the problem of frequent changes in water head during the flood season of the bulb-type hydro-turbine generator set causing load fluctuations, thereby greatly improving the load regulation stability of the unit, extending the service life of the oil pump corresponding to the generator set, and at the same time increasing the service life of various mechanical components of the unit and reducing maintenance costs.

If the generator set is still in a power fluctuation state after the adjustment time is greater than the first preset period, the adjustment is exited, the opening of the guide vanes of the current generator set is maintained, and then the opening reference value of the blades corresponding to the generator set is determined based on the guide vane opening of the current generating point unit, the water head signal corresponding to the bulb-type hydro-turbine generator set and the preset synergy characteristic curve, and the blades corresponding to the generator set are adjusted based on the opening reference value; When the difference between the real-time power generation power of the bulb-type hydro-turbine generator set and the preset power generation power given value of the bulb-type hydro-turbine generator set is greater than the second power preset value and less than or equal to the first power preset value, the opening of the guide vanes and the paddles of the generator set is adjusted. If the generator set is still in a power fluctuation state after the adjustment time is greater than the second preset period, the adjustment is exited and the opening of the guide vanes of the current generator set is maintained. Then, based on the guide vane opening of the current generating point unit, the corresponding head signal of the bulb-type hydro-turbine generator set and the preset synergistic characteristic curve, the opening reference value of the paddles corresponding to the generator set is determined, and the paddles corresponding to the generator set are adjusted based on the opening reference value.

4. The device according to claim 3, characterized in that The adjustment module is specifically used for: Step F1: if the generator set does not experience power fluctuation, determine the guide vane opening reference value based on the difference, and then adjust the current guide vane opening of the generator set to the reference value; and process the water head signal corresponding to the bulb-type hydro-turbine generator set to obtain a water head sampling value after interference removal; Step F2: using a preset synergy characteristic curve to calculate the opening reference value of the guide vane and the opening reference value of the blade corresponding to the generator set under the head sampling value after interference is removed, and adjusting the blade corresponding to the generator set based on the opening reference value; Step F3: When the real-time power generation of the generator set is equal to the preset power generation set value of the bulb-type hydro-turbine generator set, the load regulation ends; otherwise, the power generation set value of the bulb-type hydro-turbine generator set is newly set, and the process returns to step F1.
