Technical Field
The invention relates to the field of electric automation and energy control, in particular to a dynamic energy consumption control system for cooling water of a proton heavy ion accelerator.
Background
Proton heavy ion accelerators are large medical devices used in tumor radiotherapy. The proton heavy ion accelerator equipment and the supporting facilities thereof belong to high-energy consumption equipment, and take a Shanghai market proton heavy ion hospital as an example, only the proton heavy ion accelerator and a cooling water system thereof consume about 1000 ten thousand degrees in annual energy. Therefore, effective energy management is significant. However, in order to meet the requirement of 24-hour full-year normal operation of the proton heavy ion accelerator, the cooling water system is always in a full-load operation state, and the full-load operation of the cooling water system inevitably causes waste of electricity when the proton heavy ion accelerator is in a standby or stop state. The cooling water system and the proton heavy ion accelerator have a plurality of linkage signals, and if the starting and stopping of the cooling water system equipment are controlled by the manual operation of an operator, the energy saving is realized, and the safety operation risk of the proton heavy ion accelerator is caused. Therefore, a set of dynamic electricity consumption control system for cooling water of the proton heavy ion accelerator is researched and designed, the automatic start and stop control of equipment is realized, and the system is necessary for optimizing the energy consumption.
The main problems of the prior art include that the cooling water system is in a full-load operation state for 24 hours in the whole year in order to meet the operation of the proton heavy ion accelerator. However, when the accelerator is on standby or off, the cooling water system is wasteful of electricity consumption due to a low heat generation amount. In addition, no complete electricity monitoring and energy consumption optimizing control mode exists at present, and for energy consumption control, the operation of equipment is carried out only by relying on experience of engineers and operators, so that the risk of safe operation of the equipment exists. For example, the accelerator suddenly increases load and the operator is not able to timely take effective action, resulting in the heat of the accelerator not being properly carried away, and most likely causing damage to the accelerator equipment.

The natural heat exchange circulating water temperature sensor 64 is used for detecting the temperature of the natural heat exchange circulating water in real time.
All control signals of the natural heat exchange circulating water module are connected to the natural heat exchange module controller 59 and transmitted to the data exchange 61 through the network signal transmission unit IV 60.
The cold source module comprises a cold source chilled water pump I44, a cold source chilled water pump II45, a refrigerator I46, a refrigerator II47, a cold source cooling water pump I48, a cold source cooling water pump II49, an open cooling tower III fan 50, an open cooling tower II fan 51 and an open cooling tower III fan 52, wherein the chilled water temperature is detected in real time through a cold source chilled water temperature sensor 65, and the cold source cooling water temperature is detected in real time through a cold source cooling water temperature sensor 66.
All control signals of the cold source module are accessed to the cold source module controller 55 and transmitted to the data switch 61 through the network signal transmission unit III 58.

The critical temperature of heat exchange can be realized through experimental analysis of natural heat exchange circulating water, namely, the critical value T6 of the environmental temperature detected by the environmental temperature sensor 12, namely, when the environmental temperature is greater than T6, the closed cooling tower can not radiate heat.
When all the current and temperature values are below the threshold temperature, the accelerator is considered to be in a standby state, and at this time, the main controller 62 starts to count 600 seconds, and if any current or temperature value is above the threshold value within 600 seconds, the timer is cleared. If all the currents and the temperatures are still lower than the critical value after 600 seconds are finished, the refrigerator, the cold source cooling water pump and the cold source freezing water pump are sequentially turned off. The natural heat exchange module is changed from three pumps to two pumps to operate, and the system enters an energy-saving mode. In the energy-saving mode, when any current or temperature value is detected to be higher than a critical value, the cold source cooling water pump, the cold source freezing water pump and the refrigerator are sequentially started, the natural heat exchange module is changed from two pumps to three pumps for operation, and the system enters a normal operation state.
In the energy-saving mode, the open cooling tower III fan 50, the open cooling tower II fan 51 and the open cooling tower III fan 52 are in a stop state. In the normal operation state, the fan is controlled to start and stop in 4 sections according to the temperature value detected by the cold source cooling water temperature sensor 66.

The operation of the open cooling tower fan is optimized through four-section temperature control, so that the energy consumption is optimized.
The natural heat exchange module controls the start and stop of the closed cooling tower I spray water pump 35, the closed cooling tower I fan 36, the closed cooling tower II spray water pump 37, the closed cooling tower II fan 38, the closed cooling tower III spray water pump 39 and the closed cooling tower III fan 40 by four sections according to the temperature value detected by the natural heat exchange circulating water temperature sensor 64. For example, the four-stage temperatures include three critical values of 24 ℃, 24.5 ℃ and 25 ℃, respectively, when the temperature value detected by the natural heat exchange circulation water temperature sensor 64 is less than 24 ℃, the fan and the spray pump of the closed cooling tower are all stopped, when the temperature value detected by the natural heat exchange circulation water temperature sensor 64 is between 24 ℃ and 24.5 ℃, the fan and the spray pump of the closed cooling tower operate one set, when the temperature value detected by the natural heat exchange circulation water temperature sensor 64 is between 24.5 ℃ and 25 ℃, the fan and the spray pump of the closed cooling tower operate two sets, and when the temperature value detected by the natural heat exchange circulation water temperature sensor 64 is greater than 25 ℃, the fan and the spray pump of the closed cooling tower all operate. The operation of the fan and the spray pump of the closed cooling tower is optimized through four-section temperature control, so that the energy consumption is optimized.
When the ambient temperature detected by the 12 ambient temperature sensor is greater than the critical temperature, the 62 main controller starts for 1200 seconds, when the ambient temperature detected by the 12 ambient temperature sensor is still greater than the critical temperature for 1200 seconds, the starting environment is high Wen Moshi, the 33 closed cooling tower water inlet valve is closed, and the 34 closed cooling tower bypass valve is in a full-open state. Meanwhile, all fans and spray pumps of the closed cooling towers stop running. When the ambient temperature detected by the 12 ambient temperature sensor is higher than the critical temperature, the natural heat exchange module is restored.
