Fig. 2, as the efficiency of the separator decreases, the input current also decreases, but the weakening of the efficiency of the separator not only leads to problems with structural technology and strength, but also leads to poor stability, and for these two reasons, the strength must be increased moderately.

You will find that with the values of E12, the value of each success is added or subtracted by 10, and the previous value decreases.

This stems from the fact that the resistance is within a tolerance of 20 (the accuracy represents the true ** years.)

Later tolerance values of plus or minus 5 lead to resistance to the E24 range.

Today it is very common for metal films to have 2 tolerances for general purpose types, but we tend to stick to the values of resistance in either 1, 2 or 5 E12.

Cost is the deciding factor, and many retailers are now ** as standard to accommodate stocking, and at a reasonable level of low cost, resistance between2.

You will notice that the value of each success is subtracted from the 10% value of the plus value within e12.

This stems from the fact that the ancient days were represented within 20% of the resistance (exactly).

Later the value minus the 5% tolerance and the resistance caused by e24.

Today it is commonplace for the 2% tolerance metal film type, but for universal use we tend to adhere to the E12 values of resistance at 1%, 2% or 5% tolerance.

Cost is the deciding factor, with many retailers now using 2% as standard to accommodate resistance levels while socks are reasonably costly lower.

You'll notice which success plus sign in e12 value minus 10% of the previous value of the fall in the value inside.

This originates from the true old daily as resistance as 20% tolerance (accuracy) is stated.

Later adding minus 5% of the value of tolerance leads to the E24 range of resistance.

Fairly usually today is a 2% tolerant metal film genre, but for general use we tend to stick to the E12 value tolerance of % or 5% resistance.

Fees are the deciding factor, and many retailers now have a 2% range of stocking resistance as a standard to fit supply levels as well as at a moderately low cost.

You should notice that the difference between the two connected values in e12 is 10%.

In the past, the resistance tolerance was required to be accurate to 20%, but this requirement gradually changed to 5%, which led to the emergence of the E24 series.

Although the tolerance of metal film resistors is generally accurate to 2%, for general use, we usually use the E12 series with 1%, 2%, or even 5% error resistor values.

Cost is a determining factor, and the 2% error resistor is reasonably priced and low in the market, and many retailers will choose it as a standard to adjust inventory

Next, assume that all current variables are directed by the node outflow rather than inflow, as shown in Figure 1-5c. Correspondingly, as shown in Figure 1-5, in order to measure the three current values, we connected the ammeter. Note that the positive end of the three ammeters near the node shows that the sum of the three values is 0

Thus we are able to prove that the sum of the currents flowing from the node is 0, in fact if we already know i1=i'1，i2=i''3. We can directly deduce equation 1-1b from equation 1-1a, the process is as follows: (this is not written).

Therefore, we can confirm that the two current values flowing into the node are equal to the current values flowing out of the node. Furthermore, equations 1--1c can be deduced from 1-1a, when it is known that i3=-i'3. The process is as follows, (this is not written).

Or we can take the equation 1-1b and deduce equation 1-1c, the process is as follows: (this is not written).

Basic characteristics of 1-5 node currents.

This law was first discovered by the German physicist Kirchhoff, and the current at every node in a circuit obeys this law, which we call Kirchhoff's law. It can be expressed in three ways, based on the direction of the current.

Give 5 points so hard?

Part of Quebec Hydro's (HQ) transmission system to the Centre substation is also being considered in the planned microgrid island, which will provide 15 megawatts of electricity for residential and commercial loads, partly from a 125kV line and partly from a privately owned and operated 31MW thermal power plant, which can also output the remaining power. In October 2005, the island was tested and successfully completed a 12-hour isolation experiment with an 11MW load.

Transient control and mitigation when switching to "islanding" is based on the balance of load and generation before entering the island.

Stability based on generator descent governor control.

Coordination of the protection of the "island".

Compliance with the quality of power supply for a specific load during autonomous operation.

FYI.

In the planning scheme of the island microgrid, the HQ distributed system is also fully considered as an integral part of the Centel substation. The substation supplies a total of 15 MW of residential and commercial loads, as shown in Figure 16. Part of the substation is supplied by a 125kV transmission and transformation line, while the other part is used as a starting or self-supplied power supply for a 31MW power plant to which the power station belongs, and the excess electrical energy can be exported as external power supply.

The design capacity of the islanded power grid is considered to ensure the external power demand in the event of a 125kV line failure. On October 1, 2005, according to the grid connection test requirements of 12 hours of continuous operation with an output load of 11MW, the island power grid successfully passed the test.

1. Control and temporary buffering in the operation of switching to the islanded grid, and give priority to the islanded grid when balancing the user end and the power generation end.

2. The stability is based on the accuracy of the rotor speed differential controller of the generator.

3. The island power grid is used as the coordination object during the protection action.

4. Ensure the output quality of electric energy when independent power generation is supplied to designated users.

For the microgrid islanding initiative, a portion of the HQ distribution system is connected to the distribution system of the Centel substation is also under review. Substations** load 15 MW of residential and commercial power supply (Figure 16). Substation transmission is partly provided through a 125-kV line, partly by privately owned and operated 31-MW thermal power plants, and excess power supply can also be exported.

The performance of islanding requires a precautionary power outage in the event of a 125-kV line failure. In October 2005, an islanding test was carried out and an 11-MW load was completed for 12 hours of continuous islanding.

Control and mitigation of switching transients during islanding is based on load and generation balancing before islanding. Based on the stability of the generator speed sag Governor control.

Coordinated protection of silos.

Power quality provides a specific load during autonomous operation.

7 Unbalance Faults:

A very common application of symmetrical components is to calculate the unbalanced current short circuit caused by the current. Due to this three-phase unbalanced system, the possible failures are:

1.Single-wire circuit.

2.Two-wire circuit.

3.Wire line contact.

These are considered separately.

Single-line loop failure.

The system in this case consists of a network connected to an obstacle line.

The point of failure itself consists of a set of terminals (called "a, b, c") and this fault occurs on the system.

7 Unbalance Failure.

A very common application of symmetrical components is to calculate the current generated by an unbalanced short circuit. The main possible unbalance faults in three-phase systems are:

1.Single-phase ground fault.

2.Two-phase ground fault, 3Wire-to-wire faults.

These issues should be considered separately...

Single-phase ground fault.

In this case, the system includes a network that connects to the failed line. The point of failure itself consists of a set of terminals (we can call them c"a,b,c")

7. Unbalanced fault (current goes, returns does not wait).

When calculating the current imbalance caused by short circuits, the equalization vector method is often used, and the possible unbalance faults of the 3-wire power grid system are; 1, single-wire grounding, 2, double-wire grounding, 3, line shorting, these faults are differentiated, 7, 1; As shown in Figure 10, a single-wire ground fault, the faulty system includes a fault of the connected power network, a fault point on the network terminal (we call; a, b, c) to mark the occurrence of the fault at that point in the system
