220kV transmission line of alternation currents, line length is 20km.220kV alternating current circuits parameter such as table 1：
Table 1
Initially with the system modelling decoupled in AC system side, if the unit length inductance of circuit positive sequence and zero sequence, electric capacity difference
Use L1、C1And L0、C0Represent, velocity of wave, natural impedance, the traveling wave time of its positive sequence and zero sequence then distinguish v1、Z1、t1And v0、Z0、
t0Represent.In power connecting interface application, the circuit traveling wave time for decoupling have to be larger than the total time delay T of interfacedelIf, TdelIt is worth and is
200 milliseconds, traveling wave Time Calculation is as follows：
The numerical value is clear to less than interface delay, in view of the problem that decoupling is present at short-term road, takes following solution：By upper
Formula understands that the traveling wave time τ of circuit is determined by line length l and circuit traveling wave speed v, is not changing line length
In the case of l, if increasing unit length line inductance L or electric capacity C, the purpose for increasing τ is can reach.Due to high pressure
Be connected to substantial amounts of capacitor bank on the change of current bus of DC transmission system, the capacitor bank can directly as increase C source, from
And without the need for adding extra compensating element, L' in the interface.
If increased unit length line mutual-ground capacitor is Cx, then the positive zero sequence capacitance per unit length of circuit be modified to
C' in formula1And C'0Respectively revised unit length circuit positive sequence and zero sequence electric capacity.Natural impedance Z, traveling wave time τ
And interface resistance etc. can be recalculated by revised parameter.
When unit length positive sequence electric capacity increases to 0.145021F/km, amended line parameter circuit value such as table 2：
