Embodiment Construction
[0041] The present invention will be further described below in conjunction with the accompanying drawings.
[0042] If the power equipment is dynamically adjusted according to the real-time monitored environmental data and operating load during the operation of the converter valve, not only can the extreme working conditions that may occur during the operation of the converter valve be judged in advance, but also an appropriate margin can be ensured. Degree, to meet the requirements of economy.
[0043] First, establish the converter valve cooling system model, including the converter valve tower model, the valve tower model including the internal cooling circulation pipeline and the radiator model of the external cooling system, set the environmental data and operating load, and use the converter valve tower model to perform simulation calculations , get the heat load, and establish the relationship between the heat load, the environmental data and the operating load; given ...

The invention discloses a method, a system and equipment for adjusting the operation condition of power equipment in a converter valve cooling system. The method comprises the following steps of acquiring environmental data and an operation load, acquiring the optimal circulating pump flow and the optimal cooling fan air volume according to the relation between the environment data and the operation load and the circulating pump flow and the relation between the environment data and the operation load and the cooling fan air volume, acquiring the current rotating speed of the circulating pumpand the power of the cooling fan, namely the current working condition of the power equipment, comparing the current working condition of the power equipment with the optimal working condition of thepower equipment, and adjusting the current working condition of the power equipment to the optimal working condition of the power equipment if a comparison result is inconsistent; in the operation process of the converter valve, dynamic adjustment can be conducted on power equipment according to environment data and operation loads which are monitored in real time, extreme working conditions possibly occurring in the operation process of the converter valve can be judged in advance, proper margin can be ensured to be reserved, and the requirement for economy is met.
Description
technical field [0001] The invention belongs to the technical field of high-voltage direct current transmission converter valve cooling, and in particular relates to a method, system and equipment for adjusting the operating conditions of power equipment in a converter valve cooling system. Background technique [0002] The converter valve is a direct device for AC and DC conversion. It is composed of thyristors, damping capacitors, voltage equalizing capacitors, damping resistors, voltage equalizing resistors, saturable reactors, thyristor control units and other components. It has many components and complex structures. Various components in the process will generate a lot of heat, and its cooling system capability is particularly important. In order to ensure the safe and reliable operation of the converter valve, for the structure of the converter valve, the cooling method adopted in the actual project is a combination of internal cooling system and external cooling syst...
