As shown in fig. 1, in normal operation of the conventional high-temperature pile emergency power system, a normal power supply a supplies power to an emergency bus B1. When the normal power supply A is not available, the emergency generator G is started to supply power for the emergency bus B1. The uninterruptible power supply system 1 receives power from the emergency bus B1 and simultaneously supplies power to the safety bus B2. The uninterruptible power supply system 1 comprises energy storage equipment, the electric energy received from the emergency bus B1 can be stored, and when the normal power supply A is disconnected and the emergency generator G is started but the power of the emergency generator G does not reach the power meeting the requirements, the energy storage equipment in the uninterruptible power supply system 1 supplies power to the safety bus 2. The safety bus B2 is connected to the power end 21 and the control end 22 of the safety load 2 at the downstream thereof, respectively, and provides ac power for the power circuit and the control circuit of the safety load 2.
In the operation process of the existing emergency power system, the inventor finds that a plurality of problems exist when the control loop uses alternating current for power supply, for example, due to the characteristics of alternating current, electromagnetic interference is generated on surrounding cables in the transmission process, so that the ground voltage of part of elements in the control loop is increased, and misoperation of the control loop is caused by high level, so that equipment in a power loop is affected; because the power system adopts alternating current power supply in a large area, when an external alternating current circuit or a control circuit itself fails, such as a ground fault, the control circuit fails, and each device in the power circuit loses control and detection of the control circuit, so that serious safety accidents can be developed.
To solve the above-mentioned problems, embodiments of the present disclosure provide a high-temperature stack emergency power system that can provide a direct-current power supply for a control circuit.
As shown in fig. 2, a high temperature stack emergency power system of an embodiment of the present disclosure includes an emergency generator G, an emergency bus B1, an uninterruptible power supply system 1, a safety bus B2, a safety load 2, and a direct current power supply circuit 3. The input end of the emergency bus B1 is electrically connected with the emergency generator G, and the output end of the emergency bus B1 is electrically connected with the input ends of the uninterrupted power supply system 1 and the direct current power supply circuit 3 respectively. The input end of the safety bus B2 is electrically connected with the output end of the uninterruptible power supply system 1, and the output end of the safety bus B2 is electrically connected with the power end 21 of the safety load 2.

The dc power supply circuit 3 includes an ac/dc conversion device, which is configured to convert the ac power of the emergency bus B1 into dc power, and transmit the dc power to the control circuit of the safety load 2.
According to the high-temperature pile emergency power system, through the arrangement of the direct-current power supply circuit, alternating current in the system is converted into direct current, and power supply of a control loop of a load at the downstream of the safety bus is achieved. The direct current has stable performance in the transmission process, so that equipment in the control loop is not easy to generate misoperation, and meanwhile, the control loop is prevented from failure when an alternating current circuit breaks down.

Specifically, a charging breaker Q1 is provided between the emergency bus B1 and the dc charger 31, and the connection between the emergency bus B1 and the dc charger 31 can be opened and closed. When the direct current charger 31 fails upstream, the direct current charger 31 cannot output electric energy, and therefore when the storage battery 31 is required to discharge, the charging circuit breaker Q1 can be switched off, the influence of the upstream failure on the direct current power supply circuit 3 is prevented, meanwhile, the electric energy of the storage battery 31 is ensured to be completely output to the downstream safety load 2, the reverse feedback to the upstream through the direct current charger 31 is avoided, and the utilization efficiency of the electric energy is improved.
Illustratively, referring to FIG. 2, the system further includes a control switch Q2. The control switch Q2 is electrically connected to the control terminal 22 of the safety load 2 and the dc power supply circuit 3, respectively.
Specifically, a control switch Q2 is provided in the circuit between the safety load 2 and the dc power supply circuit 3 for connecting or disconnecting the safety load 2 to the dc power supply circuit 3. When the direct current power supply circuit 3 fails and causes the conditions of over-high voltage, over-high current and the like, the control switch Q2 can be utilized to disconnect the control switch Q2 from the safety load 2 in time, so that the equipment in the control loop of the safety load 2 is prevented from being influenced, and the safety of a power system is improved.

Illustratively, as shown in fig. 7, the uninterruptible power supply system 1 includes an uninterruptible power supply 11 and a second battery 12. The uninterruptible power supply 11 is electrically connected with the output end of the emergency bus B1 and the input end of the safety bus B2 respectively. The second battery 12 is electrically connected to the uninterruptible power supply 11.
Specifically, the second battery 12 serves as an energy storage device that stores electric energy input from the uninterruptible power supply 11. The ups 11 may include ac/dc conversion devices to convert ac power received from the emergency bus B1 into dc power, and input the dc power into the battery 12 for storage, and the ac power from the emergency bus B1 is also transmitted to the safety bus B2 through the ups 11. When the emergency bus B1 loses power or the electric energy quality does not reach the standard, the second storage battery 12 inverts direct current into alternating current through an alternating current-direct current conversion device in the uninterruptible power supply 11, the uninterruptible power supply 11 transmits electric energy to the safety bus B2, and finally the electric energy is supplied to all alternating current devices in a power loop of the safety load 2.

Specifically, a generator outlet switch Q4 is provided at the output of the emergency generator G. The emergency generator G is used as an emergency means after the normal power supply A fails, and is started only after the emergency bus B1 is detected to lose power. There must be a delay in time from the detection of the loss of power to the start of the emergency generator G of the emergency bus B1, and it takes a certain time from the start to the achievement of the standard required for the electric power system. Therefore, under the condition that the normal power supply is in normal operation and before the generated power in the emergency condition reaches the standard, the connection of the emergency generator G and the emergency bus B1 is disconnected by the generator outlet switch Q4, so that the negative influence of unstable power output on the power system in the false start or start process of the emergency generator G is avoided.
According to the high-temperature pile emergency power system, the outlet switch is arranged at the outlet of the emergency generator, so that the safety and stability of the power system are further improved.

In addition, before the emergency power system is modified and a direct current power supply circuit is additionally arranged, the power of a normal power supply and the power of an emergency generator also need to be calculated to meet the requirements. In this regard, on-load tests may be performed on the normal power supply and the emergency generator, respectively, to verify.
