Put the switch or the outlet in the disconnect position to make the generator idle. 5.2.2 Set the output pressure gauge or multimeter to measure the voltage or connect it to the generator auxiliary line. 5.2,3 Open the water column or door slowly. When the medium pressure rise rate is close to the rated voltage, stop opening and check whether the signal transmission is normal. If the machine reaches the new set speed and there is still no electricity, the valve should be closed immediately and the machine should be stopped to check whether the generator is connected correctly and whether the output load circuit is connected correctly.
5.3 System debugging
5.3.1 During the water flow test, the stop belt is found and the system can be tested only after the power is turned on. 5.3.2 Items to be checked, tested and adjusted during system debugging: a) Check of power generation capacity; b) Check of negative gear change; d) Inspection and adjustment of voltage regulation rate; e) Inspection of operating status.
5.3.3 Inspection of generating capacity: Slowly open the gate in the empty state of the generator. When the intermediate pressure reaches the rated value, gradually increase the load and discharge volume until the gate is fully opened. Adjust the load so that the power ratio reaches the rated value. The load at this time is the maximum generating capacity under the current state of the power station. If the power generation exceeds 2% of the rated power generation of the unit, the water volume should be immediately reduced. The maximum power generation capacity can be set as the center to prevent the generator from working under load for a long time. The power generation capacity is less than the design capacity. Check whether the water inlet is cold and dry, whether the water pipe is blocked, whether the unit is running with resistance, etc., and try again after eliminating the problem. 5.3.4 Inspection of load state: Before the unit is put into operation, the user's power consumption should be investigated and counted. A reasonable allocation plan and management system should be formulated to avoid artificial overload and low operation rate. When supplying power for the first time, special attention should be paid to whether there is a core break or short circuit. After ensuring that the power supply has stopped for a while, the voltage and voltage should be measured to estimate the wire loss. 5.3.5 During rated operation, under short-circuit conditions, according to the requirements and adjustment methods in the machine manual, the voltage and frequency of the unit should be adjusted to within the rated voltage range.
5.3.6 Inspection and fullness of steady-state power adjustment rate: The inspection of steady-state power adjustment rate should be carried out in accordance with the requirements and methods of B/T175221SS8 and
23-3, and the inspection should be carried out in accordance with the requirements and methods in the unit manual. 5.3.7 Inspection of operating status:

or the water supply mechanism has a silver movement phenomenon: Under rated working conditions, continue to run: measure the surface pressure of the generator at h2. Under normal conditions, the surface pressure of the generator should not be higher than the ambient temperature (such as 5). If the power circuit is higher than the ambient humidity 0, take the reverse wind and heat conditions to solve it: If the temperature of the generator is too high, it should be verified that the generator winding is wrong, short circuit wiring is wrong. 6.1 Operation and maintenance
