The present invention relates to a construction method and operation method of a circulating power plant system using river water. In particular, even in dry inland regions, river water inlet-8 using river water and land at different heights is used, and water level gauge-8A and screen-9 are also installed. Connect the inclined waterway-10 pipe to the water intake port, install valve-11, construct water intake port-1 at a height of 50m and outlet port-2 at a height of 30m, install water level gauge-2A, firmly install drop pipe-4 at 70m, and valve-3. Install the surge tank-12 to exhaust the air gap that occurs in the drop pipe, install the power generation starting valve-5, connect it to the water turbine-30, install the generator-31, rotor-32, hydraulic panel-14, and discharge pipe- Step 1 to complete the hydraulic facility by connecting 6 with the water turbine-31 outlet and the river water inlet-8 and installing the discharge valve-7:

When hydraulic power facilities are constructed in this way, electric transmission and transmission facilities busbars - 33, circuit breakers - 34, on-site transformers - 35, rotor transformers - 36, peripheral transformers - 37, transmission circuit breakers - 38, transmission control units - 39, and transmission towers - 40 are installed to generate power plants. Step 2 of completion of transmission and reception equipment installation:

The above step is the hydraulic power facility and transmission/receipt facility of Fig. 1, and when the power plant is operated as the facility of Fig. 2, a generator protection facility and a reverse pressurization facility for power generation of Fig. 3 are installed and controlled by connecting to the transmission/receipt facility. 3 steps to protect the substation and peripheral voltage control by operation

Figure 4 shows that when the power is received by reverse pressurization of the power plant, the power received is converted and charged to the power plant operation equipment, and the on-site transformer-35 and ADC-charging panel equipment, etc., which supply operation power and operation control power, are installed to control and protect the operation power. Step 4: Apply control power:

Panel-48 Substation operation panel-49 Water level panel-50 Five stages consisting of:

Figure-6 When installing the generator hydraulic panel-14 and the generator synchronous motor control panel-15 to fill the initial river water at the intake port-1 and outlet-2, drive the generator-31 with a synchronous motor to fill the intake port and outlet with river water at full water level. Open valve-3 and valve-11 to rotate the water turbine-30 and open valve-5. When the flow is supplied and controlled by the servo valve, it is discharged to discharge pipe-6, and discharge valve-7 opens at the discharge pressure and enters the river water inlet. When discharged at -8, river water is continuously supplied to the intake port through inclined pipe-10, and it continuously falls at outlet-2 without an air gap, and the power generation discharge flows in and is registered as a patent in the field of invention patent technology for a circulating hydroelectric power plant using river water that operates in a circular manner. This is a technical field that must be protected.

In the above background technology field, construction using land to supply generated power by constructing a circulating power plant using river water on land near a river or sea is constructed in a way that satisfies the objectives of the economic aspect and technical field. In order to do so, construct a river inlet-8 using land, install inclined pipe-10 and valve-11, connect it to the water intake, build a water intake outlet tower and operating unit, construct a power generation unit, install a power generation turbine, and connect the outlet and the water turbine. Step 1 of connecting pipe-4 and connecting discharge pipe-6, which connects water turbine-30 and the river water inlet:

The initial filling of the water intake and outlet is a two-step process of filling the river water circulation hydroelectric power plant, which fills the water intake outlet to full water level by pumping river water inlet using a generator with a synchronous motor:

When the above 1/2 stage is completed and the power generation equipment protection equipment begins to operate electrically, the main generator and protection relay are installed, and the protection equipment completes the operation test and prepares for operation before starting operation (Figure 2). (reference),Step 3:

The power transmission and reception power for operating the power plant prepared in this way is back-pressurized from the substation transmission tower and back-pressurized to the substation power supply equipment, which in turn pressurizes the main transformer, in-house transformer, and rotor transformer, and the protected substation equipment is monitored on the substation operation panel-49. This is a facility that is controlled and protected by program installation, and is controlled by compatible operation in the power plant operation panel-47 (illustrated in Figure 3, refer to), step 4:

As an electrical facility that supplies power plant operation power to operate the pressurized power plant above, AC-480V construction power is supplied to substation circuit breakers 38/3900, peripheral transformers - 37, transformers - 35/36, operating power and substation control panel - 39/39-1. Control power supply ADC-35-3B charging box for supplying 220V is charged and control power is supplied to reverse pressurize the substation. When the on-site transformer-35 is pressurized, even if the construction power is removed, the substation breaker is mechanically turned on and the control power is supplied without tripping the breaker. Since it is charged and the power is maintained for up to 2 hours, it does not trip, so remove the AC-480V construction power supply and turn on the pressurized faucet power at the 35-1 35-1A/B circuit breaker. When the faucet power is pressurized, run the program in the electric operation panel-48. By operating the electrical equipment and operating the power plant operation panel -47, the equipment is normally pressurized and integrated operation is controlled by the power plant operation panel -47 (illustrated in Figure 4, refer to Figure 4). step:

When power generation preparations are completed by supply from Figure 4, rotor control panel - 41, frequency control panel - 42, power generation control panel - 43, circuit breaker control panel - 44, substation control panel - 39/ for operation control from Figure 5 power plant operation panel - 47. 39-1 Since it is operated under normal pressure, the power plant control panel-47 controls the electrical equipment of the power plant's hydraulic equipment and opens valve-3 and valve-11 simultaneously to start operation. The flow rate in drop pipe-4 moves a lot and flows to water intake port-1. Since the flow must also flow in at the same time, it is opened simultaneously, valve-5 is opened, and the servo valve is opened by 50% by controlling the power generation control panel-43. When the water turbine-30 is rotated, discharge valve-7 opens at the pressure of discharge pipe-6 and the river water inlet- When discharged to 8, the frequency control panel-42 receives the generated voltage P-2 and controls the already supplied P-1 receiving voltage and the rotor control panel-41 voltage for frequency control with an AC-exciter, in the range of 5-20%. Step 6: Variable the rotor excitation voltage, increase the flow rate of the power generation control panel-43 servo valve, and turn on breaker 34 if the frequency control panel AFC-automatic controller is in phase at 60HZ:

When controlled and operated from the power generation control panel-47 in Figure-5, it operates in accordance with the system. However, if the rotor control and power generation control are operated with a discrepancy in the excitation voltage variation and flow control optimization, the zero phase current in the generator increases and the frequency decreases, so the rotation frequency decreases. The electronic excitation voltage variable and flow control variable must be optimized for operation, and operation exceeding 20% of the zero-phase current range can cause problems with overheating of the generator and rotor, so the generator must be protected by blocking the circuit breaker.

The problem to be solved by the present invention is civil engineering work that requires installing a power plant structure inland near a river with abundant river water. A site that does not cause problems with the river inlet and power generation structure step construction is selected and is a good site for creating water intakes and outlets. This is a task to be solved by selecting a site, preparing for natural disasters, and preparing for economical construction costs and safety.

Conventional hydroelectric power generation or pumped storage power generation requires high construction costs and high flow rate usage in the mountains to generate power using altitude differences, so as a way to solve the short power generation time, build a power plant on land near a river stream to solve the problem of construction cost and water use. can do.

The river water circulation power plant builds an inclined channel and intake port to use the abundant flow of the river, and when the moving energy of the river is transferred to the inclined channel through a step, it is quickly moved to the intake port and fills the water intake port 80m away. If it is dropped on a power generation turbine to generate power and discharged, the discharge height is discharged into a wide river inlet within 10 seconds, filling the river, and the 30m river water level is continuously filled at the 80m intake and outlet, and continues to fall and generate power for 24 hours. This is the problem that the invention aims to solve, which generates power with a small amount of power without blocking the dam by discharging it into the inlet.

The challenges to be solved for operating precise power generation equipment in the above technical field include installing special steel 2507 duplex pipes in seawater as the material for drop pipes that generate power by dropping large flow rates within 10 seconds to withstand seawater and installing large pipes without vibration. Step 1 to prevent vibration from reaching the water turbine:

The number of orders to contribute to the stability of power generation facilities is tripled, and the installation of a hydraulic panel (hydraulic panel) follows the system of the frequency control panel-42 and connects the rotor control panel-41 and the power generation control panel-43 to control the discharge pipe for precise operation. Since power generation is pushed by drop pressure without an air gap, the method of alleviating vibration in the generator water turbine is that air is sucked into the water wheel when discharged into the atmosphere of existing hydroelectric power generation, causing high vibration and if the water column is too large, it is a factor that undermines the stability of the power generation unit. 2nd step: fast discharge within 10 seconds even with low water column contributes to the stability of the power generation turbine and eliminates vibration in the water column:

2(Tw) 위의지수가 2배 커야 한다.한편 가버너 안정성이 우수한 것으로 판단할수 있다. Therefore, governor stability can be judged by the stability index, where Tm is the startup time of the machine, the time for the rotational speed of the power generation equipment to reach the normal operating speed from 0, and Tw = the startup time in the water column, when the water column is at a standstill (flow speed 0). It is the time until it accelerates to the maximum flow velocity (V). In order for any power generation facility to operate independently and perform load following and frequency regulation functions, Tm

2(Tw) The above index should be twice as large. Meanwhile, it can be judged that the governor stability is excellent.

589=9초 이므로 10초 범위내로 주파수기동 0~V 까지 이고 수주에 기동시간은 피크타임시 0~30% 범위내 회전자 제어AC-여자기로 승속 하기위한 유량이 필요 하므로 3배의 배관유량을 설계에 반영되었고 수주에 기동시간을 안정되게 해주는3단계. Therefore, by installing the start-up time drop and discharge piping within a range of 200m, the discharge time from the water intake to the discharge port is discharged within 10 seconds, and the start-up time is fastened to 600 rpm, so the generator rotor frequency can be adjusted from 0 to V within 10 seconds. If you calculate it by referring to the order start-up time calculation below, Tw=188mx28.3

Since 589 = 9 seconds, the frequency starting is 0 to V within the 10 second range, and the starting time is within the range of 0 to 30% at peak time. As the flow rate is required to increase speed with the rotor control AC-exciter, 3 times the piping flow rate is required. Step 3, which was reflected in the design and stabilized start-up time over several weeks.

The above Tw= is the machine startup time, and it can be seen that the 600rpm generator rotor frequency can be adjusted from 0 to V within 10 seconds by referring to the machine startup time calculation below.

Tw 9초로 안정적인 낙차수주로 발전설비의 회전부 중량에 회전함을 제작사가 제공하는게 정확 하지만 개략적으로 아래 터빈과 발전기에 대한값을 추정할수있는 터빈은발전기 1/10 무게로서 아래와같다. 해결 4단계: So Tm 7.4 seconds

It is accurate for the manufacturer to provide the rotation according to the weight of the rotating part of the power generation facility with a stable falling water column of Tw 9 seconds, but roughly, the turbine and generator values below can be estimated as 1/10 the weight of the generator as follows. 4 steps to solve:

Based on the fact that the rotor weight and the generator weight are manufactured with a difference of 10 times as shown above, in order to stabilize the governor, the water column startup time is 9.5 seconds - 7.5 seconds machine startup time = 2 seconds, and the water column startup time does not exceed 2.5 seconds, so the piping is maintained. There is no need to increase the emissions after power generation. Since it is discharged at the same level as the river water inlet height, river water is continuously discharged at the river water inlet at a discharge height of approximately 30m, and vibration flow control, rotor excitation control, and balance of the water wheel due to excessive water column are also minimized to ensure stable and continuous power generation without air gaps. There are five steps to solving the problem of invention technology.

It was constructed through a process to solve the background technology in the technology field of a circulating power plant using river water, and the water intake and outlet of the power generation unit with a sloped waterway to draw river water using technological inventions were constructed using safe land, making it safe due to the vulnerability of marine construction. It has a great effect in preparing for accidents and increasing the economic feasibility of power plant construction. In particular, by constructing it on the four major rivers, a large amount of river water is circulated for power generation, and contaminated water and green algae are decomposed and sprayed with chlorine, which disinfects the river water and generates eco-friendly power. We are applying for an invention patent by designing a power plant to maximize the effect of the economical and effective invention of constructing a river water circulation power plant on land that produces energy. If you give priority to the examination and register, the invention patent will have a great effect in saving the environment.
