Description

Technical Field

[0001] This invention belongs to the field of generator technology and relates to a method for measuring the amount of hydrogen leakage in the stator cooling water tank of a nitrogen-filled water-hydrogen generator. Background Technology

[0002] Currently, large-capacity salient-pole synchronous generators mainly use a water-hydrogen-hydrogen cooling method. Under operating conditions, the internal hydrogen pressure of the generator is greater than the stator cooling water pressure. Hydrogen enters the stator cooling water tank through the hollow conductors of the stator bars. The amount of hydrogen leakage in the stator cooling water tank can effectively provide early warning of micro-leakage faults in the stator bars and water-electric connectors.

[0003] Nitrogen-filled stator cooling water tanks can effectively reduce the oxygen content in the stator cooling water tank, improve the quality of stator cooling water, and reduce the risk of hydrogen-oxygen mixing in the tank. However, they can only monitor the hydrogen concentration in the gas inside the tank and cannot directly detect the amount of hydrogen leakage inside the tank, which affects the early warning efficiency for micro-leakage faults in stator bars and water and electricity joints.

[0004] Furthermore, for nitrogen-filled stator cooling water tanks, the hydrogen concentration within the tank can provide early warning of minor leaks in the stator windings and water-electrical connections, but this requires continuously keeping the tank's vent valve open. Currently, many nitrogen-filled stator cooling water tanks in water-hydrogen generators still do not have their vent pipes extended to the top of the plant. Measuring these vents under dynamic stability conditions with the vent valve open may lead to hydrogen accumulation within the plant. Additionally, some nitrogen-filled stator cooling water tanks have relatively thin vent pipe diameters, which can cause short-term fluctuations in measurement data when using dynamic stability methods. Modifying the stator cooling water tanks to address these issues will increase both financial and time costs. Summary of the Invention

[0005] This invention addresses the problems existing in the prior art by proposing a method and device for measuring hydrogen leakage in the cooling water tank of a water-hydrogen generator. The purpose is to overcome the inaccuracy in measuring hydrogen leakage in the nitrogen-filled stator cooling water tank of existing water-hydrogen generators and to avoid the safety risks of hydrogen accumulation.

[0009] The first hydrogen leakage amount is obtained by calculating the total amount of new gas in the stator cooling water tank during the first time interval.

[0010] The second hydrogen leakage amount is obtained based on the total amount of new hydrogen gas added in the stator cooling water tank during the time period calculated in the first time interval.

[0011] If the difference between the first and second hydrogen leakage amounts is less than or equal to a preset value relative to the maximum value of the first and second hydrogen leakage amounts, the average of the first and second hydrogen leakage amounts will be used as the final hydrogen leakage amount.

[0012] If the difference between the first and second hydrogen leakage amounts is greater than a preset value relative to the maximum value of the first and second hydrogen leakage amounts, the non-ideal gas in the stator cooling water tank is simulated to diffuse into the ideal gas, and the first and second hydrogen leakage amounts are recalculated until the difference between the first and second hydrogen leakage amounts is less than or equal to the preset value relative to the maximum value of the first and second hydrogen leakage amounts.

[0043] Figure 1 This is a schematic diagram of the hydrogen leakage calculation process. Detailed Implementation

[0044] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0045] Example 1

[0046] This embodiment provides a method for measuring hydrogen leakage in the nitrogen-filled cooling water tank of a water-hydrogen generator, including the following steps:

[0047] S1. Close the exhaust valve of the stator cooling water tank and stop charging nitrogen into the stator cooling water tank to make the stator cooling water tank a closed state.

[0048] Determine the first time interval [t] a , t z At time point t a Stop charging nitrogen into the stator cooling water tank. When the gas pressure in the stator cooling water tank reaches the preset value, record the time point t. z At time point t z Open the vent valve. The preset value of the gas pressure in the stator cooling water tank can be the maximum safe threshold for the gas pressure in the stator cooling water tank.

[0049] Within the first time interval, the gas pressure, hydrogen concentration, gas volume, and stator bar cooling water inlet temperature in the stator cooling water tank are continuously monitored and recorded. During normal operation of the water-hydrogen generator, it is necessary to monitor the stator bar cooling water inlet temperature flowing from the stator cooling water tank to the stator bars, and simultaneously monitor the stator bar cooling water outlet temperature flowing from the stator bars to the stator cooling water tank, thereby monitoring the cooling effect of the cooling water. Measuring the amount of hydrogen leakage in the stator cooling water tank requires detecting the water temperature of the stator cooling water tank. In this embodiment, the stator bar cooling water inlet temperature is used as the stator cooling water tank temperature, which avoids the need to install an additional temperature sensor in the stator cooling water tank, reducing measurement costs.

[0050] S2. Based on the total amount of new gas added in the stator cooling water tank during the first time interval, obtain the first hydrogen leakage amount. The first hydrogen leakage amount at this time is the primary first hydrogen leakage amount.

[0051] The initial hydrogen leakage rate is calculated based on the gas pressure and volume in the stator cooling water tank and the inlet water temperature of the stator winding bars. Specifically, the starting point t for calculating the hydrogen leakage rate is selected as the time point when the gas pressure or hydrogen concentration in the stator cooling water tank has not continued to rise. s , t a ≤t s <t z At this time, the gas pressure in the stator cooling water tank is recorded as P. s The volume of gas in the stator cooling water tank is V. s Atmospheric pressure B s Average temperature of stator bar cooling water inlet (K) s The corresponding thermodynamic temperature T s T s =Ks +273, K is For t s The time point is the i-th stator bar cooling water inlet temperature measuring point of the generator, where m is the number of stator bar cooling water inlet temperature measuring points.

[0052] Choose the end time point t for hydrogen leakage calculation e , t a ≤t s <t e ≤t z At this time, the gas pressure in the stator cooling water tank is recorded as P. e The volume of gas in the stator cooling water tank is V. e Atmospheric pressure B e Average temperature of stator bar cooling water inlet (K) e The corresponding thermodynamic temperature T e T e =K e +273, K ie For t e The time point is the i-th stator bar cooling water inlet temperature measuring point of the generator, where m is the number of stator bar cooling water inlet temperature measuring points, and the calculation time period is [t]. s , t e ].

[0053] The initial hydrogen leakage H1 is:

[0054]

[0055] S3. Based on the total amount of new hydrogen gas added in the stator cooling water tank during the time period calculated in the first time interval, obtain the second hydrogen leakage amount.

[0056] The second hydrogen leakage in the primary stage is calculated based on the gas pressure, hydrogen concentration, gas volume, and stator bar cooling water inlet temperature in the stator cooling water tank.

[0057] Time point t s The hydrogen concentration in the stator cooling water tank is N s Time point t e The hydrogen concentration in the stator cooling water tank is N e ,

[0058] The initial hydrogen leakage H2 is:

[0059]

[0060] S4. Compare the relationship between the difference between the first and second hydrogen leakage amounts and the percentage of the maximum value between the first and second hydrogen leakage amounts with the preset value.

[0061] In this embodiment, the preset value is 0.05. (Specific comparison...) The relationship with 0.05, where Max represents the maximum value of the sequence. When This indicates that the difference in hydrogen leakage calculated based on the total amount of newly added gas and the total amount of newly added hydrogen is small, and the gas distribution in the stator cooling water tank is close to ideal. When This indicates a significant difference in hydrogen leakage calculated based on the total amount of newly added gas and the total amount of newly added hydrogen. This is because the leaked hydrogen does not have enough time to diffuse or the hydrogen is concentrated above the nitrogen, resulting in uneven mixing of hydrogen and nitrogen. The gas in the stator cooling water tank is far from the ideal distribution and is considered a non-ideal gas.

[0062] S5. If the difference between the first and second hydrogen leakage amounts is less than or equal to a preset value relative to the maximum of the first and second hydrogen leakage amounts, the average of the first and second hydrogen leakage amounts will be used as the final hydrogen leakage amount. That is, when At that time, take This represents the final amount of hydrogen leakage.

[0063] S6. If the difference between the first and second hydrogen leakage amounts is greater than the maximum value of the first and second hydrogen leakage amounts, simulate the diffusion of non-ideal gas to ideal gas in the stator cooling water tank, and recalculate the first and second hydrogen leakage amounts until the difference between the first and second hydrogen leakage amounts is less than or equal to the maximum value of the first and second hydrogen leakage amounts.

[0064] Specifically, when At that time, the first and second hydrogen leakage amounts were calculated by simulating the diffusion cycle from a non-ideal gas to an ideal gas.

[0065] The method for simulating the diffusion cycle from a non-ideal gas to an ideal gas, i.e., the calculation of hydrogen leakage cycle, includes the following steps:

[0066] make Find P 2n+1 ;

[0067] make Find N 2n+1 ;

[0068] make When, find P 2n+2 ;

[0069] make Find N0;

[0070] make Find N 2n+2 ;

[0071] calculate and

[0072]

[0073] when hour, This represents the final amount of hydrogen leakage.

[0074] when When n is increased by 1, the simulation of the diffusion cycle from a non-ideal gas to an ideal gas is continued; when the simulation of the diffusion cycle from a non-ideal gas to an ideal gas is performed for the first time, n is 0.
