Hydropower Knowledge

We have previously introduced that the hydraulic turbine is divided into an impact turbine and an impact turbine. The classification and applicable head heights of impact turbines were also introduced before. Impact turbines can be divided into: bucket turbines, oblique impact turbines and double...Read more »

POWER PLANT TYPE VS. COST One of the core factors affecting construction costs for power generation facilities is the type of proposed facility. Construction costs can vary widely depending on whether they are coal-fired power plants or plants powered by natural gas, solar, wind, or nuclear gene...Read more »

Worldwide, hydropower plants produce about 24 percent of the world’s electricity and supply more than 1 billion people with power. The world’s hydropower plants output a combined total of 675,000 megawatts, the energy equivalent of 3.6 billion barrels of oil, according to the National...Read more »

While Europe scrambles to procure natural gas for winter power generation and heating, Norway, the largest oil and gas producer in Western Europe, faced an entirely different power problem this summer — dry weather that depleted hydroelectric reservoirs, which Electricity generation accounts for ...Read more »

A water turbine, with the Kaplan, Pelton, and Francis turbines being the most common ones, is a large rotary machine that works to convert kinetic and potential energy into hydroelectricity. These modern equivalents of the water wheel have been used for over 135 years for industrial power generat...Read more »

Hydropower is by far the largest renewable worldwide, producing over twice as much energy as wind, and over four times as much as solar. And pumping water up a hill, aka “pumped storage hydropower”, comprises well over 90% of the world’s total energy storage capacity. But in spite of hydropower’...Read more »

1、 The output of wheel generator decreases （1） Cause Under the condition of constant water head, when the guide vane opening has reached the no-load opening, but the turbine has not reached the rated speed, or when the guide vane opening is increased than the original at the same output, it ...Read more »

1、 Items to be checked before startup: 1. Check whether the inlet gate valve is fully open; 2. Check whether all cooling water is fully opened; 3. Check whether the bearing lubricating oil level is normal;Shall be located; 4. Check whether the instrument network voltage and frequency paramet...Read more »

Both hydropower and thermal power must have an exciter. The exciter is generally connected to the same large shaft as the generator. When the large shaft rotates under the drive of the prime mover, it simultaneously drives the generator and the exciter to rotate. The exciter is a DC generator tha...Read more »

Hydropower is to convert the water energy of natural rivers into electricity for people to use. There are various sources of energy used in power generation, such as solar energy, water power in rivers, and wind power generated by air flow. The cost of hydropower generation using hydropower is ch...Read more »

AC frequency is not directly related to the engine speed of hydropower station, but it is indirectly related. No matter what type of power generation equipment, it is necessary to transmit electric energy to the power grid after generating electric energy, that is, the generator needs to be conne...Read more »

ackground on the repair of turbine main shaft wear During the inspection process, the maintenance personnel of a hydropower station found that the noise of the turbine was too loud, and the temperature of the bearing continued to rise. Since the company does not have the shaft replacement condit...Read more »
