Figure 2.1-29 PSBG logic
Setting for blocking operation of Distance protection
Scheme switches [
Z*S-PSBBlk
] and [
Z*G-PSBBlk
] are provided to block the operation of the
respective Z*S and Z*G elements. Generally, it is desirable to block the operation of the
respective ZS elements and ZG elements during a power swing. Thus,
Block
is set for the
respective scheme switches [
Z*S-PSBBlk
] and [
Z*G-PSBBlk
].
However, when it is required to continue the operation of respective ZS and ZG elements
during a power swing,
Non
is set for respective scheme switches.
(ii)
Load encroachment
The load encroachment element is used to improve security when heavy load current flows in
a line. When the impedance remains within the hatched area as shown in Figure 2.1-30, a
signal that reflects the operation of the load encroachment element is yielded; respective ZS
elements are blocked to operate by blocking signals, which can be issued at which
Block
is set
for the scheme switches [
Z*S-LEBlk
].
As shown in Figure 2.1-30(a), for ZS the minimum load resistance R is defined by the
setting of scheme switches [
LESR
] and [
LESL
]. Setting of the maximum load angles across the
R ordinate is performed using scheme switches [
LESR-Angle
] and [
LESL-Angle
].
For ZG, when
Block
is set for the scheme switches [
Z*G-LEBlk
], similar settings and
scheme switches are available: settings [
LEGR
], [
LEGL
], [
LEGR-Angle
], and [
LEGL-Angle
],
